[\fIfile\fP] -+.SH DESCRIPTION -+Octave is a high-level language, primarily intended for numerical -+computations. It provides a convenient command line interface for -+solving linear and nonlinear problems numerically. \fBoctave-cli\fP -+has been compiled without any GUI support (Qt) which makes it smaller -+than the default \fBoctave\fP executable, but also limits it to -+providing just the command line interface (CLI). -+.SH OPTIONS -+The complete set of command-line options for \fBoctave-cli\fP is available -+by running the following command from the shell. -+.Vb -+ -+ octave-cli \-\-help -+.Ve -+.SH DOCUMENTATION -+The primary documentation for Octave is written using Texinfo, the GNU -+documentation system, which allows the same source files to be used to -+produce online and printed versions of the manual. -+.PP -+You can read the online copy of the Octave documentation by issuing -+the following command from within Octave. -+.Vb -+ -+ octave:1> doc -+ -+.Ve -+The Info files may also be read with a stand-alone program such as -+\fBinfo\fP or \fBxinfo\fP. HTML, Postscript, or PDF versions of the -+documentation are installed on many systems as well. -+.SH BUGS -+The Octave project maintains a bug tracker at http://bugs.octave.org. -+Before submitting a new item please read the instructions at -+http://www.octave.org/bugs.html on how to submit a useful report. -+.SH FILES -+Upon startup Octave looks for four initialization files.

 implies, as a side effect, small differences in treating zeros.

    The IEEE floating point standard defines the result of the expressions 0*Inf and 
+0*NaN as NaN. This is widely agreed to be a good
+compromise.
 Numerical software dealing with structured and sparse matrices (including
 Octave) however, almost always makes a distinction between a "numerical zero"
 and an "assumed zero".

-15.1 Introduction to Plotting
-=============================
-
-Earlier versions of Octave provided plotting through the use of gnuplot.
-This capability is still available.  But, a newer plotting capability is
-provided by access to OpenGL.  Which plotting system is used is
-controlled by the 'graphics_toolkit' function.  *Note Graphics
-Toolkits::.
-
-   The function call 'graphics_toolkit ("fltk")' selects the FLTK/OpenGL
-system, and 'graphics_toolkit ("gnuplot")' selects the gnuplot system.
-The two systems may be used selectively through the use of the
-'graphics_toolkit' property of the graphics handle for each figure.
-This is explained in *note Graphics Data Structures::.  *Caution:* The
-FLTK toolkit uses single precision variables internally which limits the
-maximum value that can be displayed to approximately 10^{38}.  If your
-data contains larger values you must use the gnuplot toolkit which
-supports values up to 10^{308}.

+=============================
+
+ -- Built-in Function: eye (N)
+ -- Built-in Function: eye (M, N)
+ -- Built-in Function: eye ([M N])
+ -- Built-in Function: eye (..., CLASS)
+     Return an identity matrix.  If invoked with a single scalar
+     argument N, return a square NxN identity matrix.  If supplied two
+     scalar arguments (M, N), 'eye' takes them to be the number of rows
+     and columns.  If given a vector with two elements, 'eye' uses the
+     values of the elements as the number of rows and columns,
+     respectively.  For example:
+
+          eye (3)
+           =>  1  0  0
+               0  1  0
+               0  0  1
+
+     The following expressions all produce the same result:
+
+          eye (2)
+          ==
+          eye (2, 2)
+          ==
+          eye (size ([1, 2; 3, 4])
+
+     The optional argument CLASS, allows 'eye' to return an array of the
+     specified type, like
+
+          val = zeros (n,m, "uint8")
+
+     Calling 'eye' with no arguments is equivalent to calling it with an
+     argument of 1.  Any negative dimensions are treated as zero.  These
+     odd definitions are for compatibility with MATLAB.
+

+ -- Built-in Function: ones (M, N, K, ...)
+ -- Built-in Function: ones ([M N ...])
+ -- Built-in Function: ones (..., CLASS)
+     Return a matrix or N-dimensional array whose elements are all 1.
+     If invoked with a single scalar integer argument N, return a square
+     NxN matrix.  If invoked with two or more scalar integer arguments,
+     or a vector of integer values, return an array with the given
+     dimensions.
+
+     If you need to create a matrix whose values are all the same, you
+     should use an expression like
+
+          val_matrix = val * ones (m, n)
+
+     The optional argument CLASS specifies the class of the return array
+     and defaults to double.  For example:
+
+          val = ones (m,n, "uint8")
+
+     See also: *note zeros: XREFzeros.

+     element.  If N is not specified, form an M by M block matrix.  For
+     copying along more than two dimensions, specify the number of times

+
+     See also: *note repelems: XREFrepelems.
+
+ -- Built-in Function: repelems (X, R)
+     Construct a vector of repeated elements from X.  R is a 2xN integer
+     matrix specifying which elements to repeat and how often to repeat
+     each element.
+
+     Entries in the first row, R(1,j), select an element to repeat.  The
+     corresponding entry in the second row, R(2,j), specifies the repeat
+     count.  If X is a matrix then the columns of X are imagined to be
+     stacked on top of each other for purposes of the selection index.
+     A row vector is always returned.
+
+     Conceptually the result is calculated as follows:
+
+          y = [];
+          for i = 1:columns (R)
+            y = [y, X(R(1,i)*ones(1, R(2,i)))];
+          endfor
+
+     See also: *note repmat: XREFrepmat, *note cat: XREFcat.
+
+   The functions 'linspace' and 'logspace' make it very easy to create
+vectors with evenly or logarithmically spaced elements.  *Note Ranges::.
+
+ -- Built-in Function: linspace (BASE, LIMIT)
+ -- Built-in Function: linspace (BASE, LIMIT, N)
+     Return a row vector with N linearly spaced elements between BASE
+     and LIMIT.  If the number of elements is greater than one, then the
+     endpoints BASE and LIMIT are always included in the range.  If BASE
+     is greater than LIMIT, the elements are stored in decreasing order.
+     If the number of points is not specified, a value of 100 is used.
+
+     The 'linspace' function always returns a row vector if both BASE
+     and LIMIT are scalars.  If one, or both, of them are column
+     vectors, 'linspace' returns a matrix.
+
+     For compatibility with MATLAB, return the second argument (LIMIT)
+     if fewer than two values are requested.
+
+     See also: *note logspace: XREFlogspace.
+
+ -- Function File: logspace (A, B)
+ -- Function File: logspace (A, B, N)
+ -- Function File: logspace (A, pi, N)
+     Return a row vector with N elements logarithmically spaced from
+     10^A to 10^B.  If N is unspecified it defaults to 50.
+
+     If B is equal to pi, the points are between 10^A and pi, _not_ 10^A
+     and 10^pi, in order to be compatible with the corresponding MATLAB
+     function.
+
+     Also for compatibility with MATLAB, return the second argument B if
+     fewer than two values are requested.

+ -- Built-in Function: V = rand ("seed")
+ -- Built-in Function: rand ("seed", V)
+ -- Built-in Function: rand ("seed", "reset")
+ -- Built-in Function: rand (..., "single")
+ -- Built-in Function: rand (..., "double")
+     Return a matrix with random elements uniformly distributed on the
+     interval (0, 1).  The arguments are handled the same as the
+     arguments for 'eye'.
+
+     You can query the state of the random number generator using the
+     form
+
+          v = rand ("state")
+
+     This returns a column vector V of length 625.  Later, you can
+     restore the random number generator to the state V using the form
+
+          rand ("state", v)
+
+     You may also initialize the state vector from an arbitrary vector
+     of length <= 625 for V.  This new state will be a hash based on the
+     value of V, not V itself.
+
+     By default, the generator is initialized from '/dev/urandom' if it
+     is available, otherwise from CPU time, wall clock time, and the
+     current fraction of a second.  Note that this differs from MATLAB,
+     which always initializes the state to the same state at startup.
+     To obtain behavior comparable to MATLAB, initialize with a
+     deterministic state vector in Octave's startup files (*note Startup
+     Files::).
+
+     To compute the pseudo-random sequence, 'rand' uses the Mersenne
+     Twister with a period of 2^{19937}-1 (See M. Matsumoto and T.
+     Nishimura, 'Mersenne Twister: A 623-dimensionally equidistributed
+     uniform pseudorandom number generator', ACM Trans.  on Modeling and
+     Computer Simulation Vol.  8, No.  1, pp.  3-30, January 1998,
+     ).  Do
+     *not* use for cryptography without securely hashing several
+     returned values together, otherwise the generator state can be
+     learned after reading 624 consecutive values.
+
+     Older versions of Octave used a different random number generator.
+     The new generator is used by default as it is significantly faster
+     than the old generator, and produces random numbers with a
+     significantly longer cycle time.  However, in some circumstances it
+     might be desirable to obtain the same random sequences as used by
+     the old generators.  To do this the keyword "seed" is used to
+     specify that the old generators should be use, as in
+
+          rand ("seed", val)
+
+     which sets the seed of the generator to VAL.  The seed of the
+     generator can be queried with
+
+          s = rand ("seed")
+
+     However, it should be noted that querying the seed will not cause
+     'rand' to use the old generators, only setting the seed will.  To
+     cause 'rand' to once again use the new generators, the keyword
+     "state" should be used to reset the state of the 'rand'.
+
+     The state or seed of the generator can be reset to a new random
+     value using the "reset" keyword.
+
+     The class of the value returned can be controlled by a trailing
+     "double" or "single" argument.  These are the only valid classes.

+ -- Function File: randi (IMAX, M, N, ...)
+ -- Function File: randi ([IMIN IMAX], ...)
+ -- Function File: randi (..., "CLASS")
+     Return random integers in the range 1:IMAX.
+
+     Additional arguments determine the shape of the return matrix.
+     When no arguments are specified a single random integer is
+     returned.  If one argument N is specified then a square matrix (N x N)
+     is returned.  Two or more arguments will return a multi-dimensional
+     matrix (M x N x ...).
+
+     The integer range may optionally be described by a two element
+     matrix with a lower and upper bound in which case the returned
+     integers will be on the interval [IMIN, IMAX].
+
+     The optional argument CLASS will return a matrix of the requested
+     type.  The default is "double".
+
+     The following example returns 150 integers in the range 1-10.
+
+          ri = randi (10, 150, 1)
+
+     Implementation Note: 'randi' relies internally on 'rand' which uses
+     class "double" to represent numbers.  This limits the maximum
+     integer (IMAX) and range (IMAX - IMIN) to the value returned by the
+     'bitmax' function.  For IEEE floating point numbers this value is
+     2^{53} - 1.

+
+   The generators operate in the new or old style together, it is not
+possible to mix the two.  Initializing any generator with "state" or
+"seed" causes the others to switch to the same style for future calls.
+
+   The state of each generator is independent and calls to different
+generators can be interleaved without affecting the final result.  For
+example,
+
+     rand ("state", [11, 22, 33]);
+     randn ("state", [44, 55, 66]);
+     u = rand (100, 1);
+     n = randn (100, 1);
+
+and
+
+     rand ("state", [11, 22, 33]);
+     randn ("state", [44, 55, 66]);
+     u = zeros (100, 1);
+     n = zeros (100, 1);
+     for i = 1:100
+       u(i) = rand ();
+       n(i) = randn ();
+     end
+
+produce equivalent results.  When the generators are initialized in the
+old style with "seed" only 'rand' and 'randn' are independent, because
+the old 'rande', 'randg' and 'randp' generators make calls to 'rand' and
+'randn'.
+
+   The generators are initialized with random states at start-up, so
+that the sequences of random numbers are not the same each time you run
+Octave.(1)  If you really do need to reproduce a sequence of numbers
+exactly, you can set the state or seed to a specific value.
+
+   If invoked without arguments, 'rand' and 'randn' return a single
+element of a random sequence.

-22.3 Iterative Techniques Applied to Sparse Matrices
-====================================================
-
-The left division '\' and right division '/' operators, discussed in the
-previous section, use direct solvers to resolve a linear equation of the
-form 'X = A \ B' or 'X = B / A'.  Octave equally includes a number of
-functions to solve sparse linear equations using iterative techniques.
-
- -- Function File: X = pcg (A, B, TOL, MAXIT, M1, M2, X0, ...)
- -- Function File: [X, FLAG, RELRES, ITER, RESVEC, EIGEST] = pcg (...)
-
-     Solve the linear system of equations 'A * X = B' by means of the
-     Preconditioned Conjugate Gradient iterative method.  The input
-     arguments are
-
-        * A can be either a square (preferably sparse) matrix or a
-          function handle, inline function or string containing the name
-          of a function which computes 'A * X'.  In principle, A should
-          be symmetric and positive definite; if 'pcg' finds A not to be
-          positive definite, a warning is printed and the FLAG output
-          will be set.
-
-        * B is the right-hand side vector.
-
-        * TOL is the required relative tolerance for the residual error,
-          'B - A * X'.  The iteration stops if
-          'norm (B - A * X)' <= TOL * norm (B).  If TOL is omitted or
-          empty then a tolerance of 1e-6 is used.
-
-        * MAXIT is the maximum allowable number of iterations; if MAXIT
-          is omitted or empty then a value of 20 is used.
-
-        * M = M1 * M2 is the (left) preconditioning matrix, so that the
-          iteration is (theoretically) equivalent to solving by 'pcg'
-          'P * X = M \ B', with 'P = M \ A'.  Note that a proper choice
-          of the preconditioner may dramatically improve the overall
-          performance of the method.  Instead of matrices M1 and M2, the
-          user may pass two functions which return the results of
-          applying the inverse of M1 and M2 to a vector (usually this is
-          the preferred way of using the preconditioner).  If M1 is
-          omitted or empty '[]' then no preconditioning is applied.  If
-          M2 is omitted, M = M1 will be used as a preconditioner.
-
-        * X0 is the initial guess.  If X0 is omitted or empty then the
-          function sets X0 to a zero vector by default.
-
-     The arguments which follow X0 are treated as parameters, and passed
-     in a proper way to any of the functions (A or M) which are passed
-     to 'pcg'.  See the examples below for further details.  The output
-     arguments are
-
-        * X is the computed approximation to the solution of
-          'A * X = B'.
-
-        * FLAG reports on the convergence.  A value of 0 means the
-          solution converged and the tolerance criterion given by TOL is
-          satisfied.  A value of 1 means that the MAXIT limit for the
-          iteration count was reached.  A value of 3 indicates that the
-          (preconditioned) matrix was found not to be positive definite.
-
-        * RELRES is the ratio of the final residual to its initial
-          value, measured in the Euclidean norm.
-
-        * ITER is the actual number of iterations performed.
-
-        * RESVEC describes the convergence history of the method.
-          'RESVEC(i,1)' is the Euclidean norm of the residual, and
-          'RESVEC(i,2)' is the preconditioned residual norm, after the
-          (I-1)-th iteration, 'I = 1, 2, ..., ITER+1'.  The
-          preconditioned residual norm is defined as 'norm (R) ^ 2 = R'
-          * (M \ R)' where 'R = B - A * X', see also the description of
-          M.  If EIGEST is not required, only 'RESVEC(:,1)' is returned.
-
-        * EIGEST returns the estimate for the smallest 'EIGEST(1)' and
-          largest 'EIGEST(2)' eigenvalues of the preconditioned matrix
-          'P = M \ A'.  In particular, if no preconditioning is used,
-          the estimates for the extreme eigenvalues of A are returned.
-          'EIGEST(1)' is an overestimate and 'EIGEST(2)' is an
-          underestimate, so that 'EIGEST(2) / EIGEST(1)' is a lower
-          bound for 'cond (P, 2)', which nevertheless in the limit
-          should theoretically be equal to the actual value of the
-          condition number.  The method which computes EIGEST works only
-          for symmetric positive definite A and M, and the user is
-          responsible for verifying this assumption.
-
-     Let us consider a trivial problem with a diagonal matrix (we
-     exploit the sparsity of A)
-
-          n = 10;
-          A = diag (sparse (1:n));
-          b = rand (n, 1);
-          [l, u, p, q] = luinc (A, 1.e-3);

-     3 since lower and upper triangular matrices are easier to invert

-     is trivial) is defined as a function

-     Two types of incomplete factorization are possible, and the type is

-
-     Called with a second argument of '0', the zero-level incomplete

-     where the position of the non-zero arguments correspond to the same
-     positions as in the matrix A.
-
-     Alternatively, the fill-in of the incomplete LU factorization can
-     be controlled through the variable DROPTOL or the structure OPTS.
-     The UMFPACK multifrontal factorization code by Tim A. Davis is used
-     for the incomplete LU factorization, (availability
-     )
-
-     DROPTOL determines the values below which the values in the LU 
-     factorization are dropped and replaced by zero.  It must be a
-     positive scalar, and any values in the factorization whose absolute
-     value are less than this value are dropped, expect if leaving them
-     increase the sparsity of the matrix.  Setting DROPTOL to zero
-     results in a complete LU factorization which is the default.
-
-     OPTS is a structure containing one or more of the fields

-     'droptol'
-          The drop tolerance as above.  If OPTS only contains 'droptol'
-          then this is equivalent to using the variable DROPTOL.
-
-     'milu'
-          A logical variable flagging whether to use the modified
-          incomplete LU  factorization.  In the case that 'milu' is
-          true, the dropped values are subtracted from the diagonal of
-          the matrix U of the factorization.  The default is 'false'.
-
-     'udiag'
-          A logical variable that flags whether zero elements on the
-          diagonal of U should be replaced with DROPTOL to attempt to
-          avoid singular factors.  The default is 'false'.
-
-     'thresh'
-          Defines the pivot threshold in the interval [0,1].  Values
-          outside that range are ignored.
-
-     All other fields in OPTS are ignored.  The outputs from 'luinc' are
-     the same as for 'lu'.
-
-     Given the string argument "vector", 'luinc' returns the values of P

+form 'X = A \ B' or 'X = B / A'.  Octave equally includes a number of
+functions to solve sparse linear equations using iterative techniques.

+
+     Solve the linear system of equations 'A * X = B' by means of the
+     Preconditioned Conjugate Gradient iterative method.  The input
+     arguments are
+
+        * A can be either a square (preferably sparse) matrix or a
+          function handle, inline function or string containing the name
+          of a function which computes 'A * X'.  In principle, A should
+          be symmetric and positive definite; if 'pcg' finds A not to be
+          positive definite, a warning is printed and the FLAG output
+          will be set.
+
+        * B is the right-hand side vector.
+
+        * TOL is the required relative tolerance for the residual error,
+          'B - A * X'.  The iteration stops if
+          'norm (B - A * X)' <= TOL * norm (B).  If TOL is omitted or
+          empty then a tolerance of 1e-6 is used.
+
+        * MAXIT is the maximum allowable number of iterations; if MAXIT
+          is omitted or empty then a value of 20 is used.
+
+        * M = M1 * M2 is the (left) preconditioning matrix, so that the
+          iteration is (theoretically) equivalent to solving by 'pcg'
+          'P * X = M \ B', with 'P = M \ A'.  Note that a proper choice
+          of the preconditioner may dramatically improve the overall
+          performance of the method.  Instead of matrices M1 and M2, the
+          user may pass two functions which return the results of
+          applying the inverse of M1 and M2 to a vector (usually this is
+          the preferred way of using the preconditioner).  If M1 is
+          omitted or empty '[]' then no preconditioning is applied.  If
+          M2 is omitted, M = M1 will be used as a preconditioner.
+
+        * X0 is the initial guess.  If X0 is omitted or empty then the
+          function sets X0 to a zero vector by default.
+
+     The arguments which follow X0 are treated as parameters, and passed
+     in a proper way to any of the functions (A or M) which are passed
+     to 'pcg'.  See the examples below for further details.  The output
+     arguments are
+
+        * X is the computed approximation to the solution of
+          'A * X = B'.
+
+        * FLAG reports on the convergence.  A value of 0 means the
+          solution converged and the tolerance criterion given by TOL is
+          satisfied.  A value of 1 means that the MAXIT limit for the
+          iteration count was reached.  A value of 3 indicates that the
+          (preconditioned) matrix was found not to be positive definite.
+
+        * RELRES is the ratio of the final residual to its initial
+          value, measured in the Euclidean norm.
+
+        * ITER is the actual number of iterations performed.
+
+        * RESVEC describes the convergence history of the method.
+          'RESVEC(i,1)' is the Euclidean norm of the residual, and
+          'RESVEC(i,2)' is the preconditioned residual norm, after the
+          (I-1)-th iteration, 'I = 1, 2, ..., ITER+1'.  The
+          preconditioned residual norm is defined as 'norm (R) ^ 2 = R'
+          * (M \ R)' where 'R = B - A * X', see also the description of
+          M.  If EIGEST is not required, only 'RESVEC(:,1)' is returned.
+
+        * EIGEST returns the estimate for the smallest 'EIGEST(1)' and
+          largest 'EIGEST(2)' eigenvalues of the preconditioned matrix
+          'P = M \ A'.  In particular, if no preconditioning is used,
+          the estimates for the extreme eigenvalues of A are returned.
+          'EIGEST(1)' is an overestimate and 'EIGEST(2)' is an
+          underestimate, so that 'EIGEST(2) / EIGEST(1)' is a lower
+          bound for 'cond (P, 2)', which nevertheless in the limit
+          should theoretically be equal to the actual value of the
+          condition number.  The method which computes EIGEST works only
+          for symmetric positive definite A and M, and the user is
+          responsible for verifying this assumption.
+
+     Let us consider a trivial problem with a diagonal matrix (we
+     exploit the sparsity of A)
+
+          n = 10;
+          A = diag (sparse (1:n));
+          b = rand (n, 1);
+          [l, u, p, q] = luinc (A, 1.e-3);

+          endfunction
+
+          x = pcg ("apply_a", b)
+

+

+     3 since lower and upper triangular matrices are easier to invert
+
+          x = pcg (A, b, 1.e-6, 500, l, u)
+
+     EXAMPLE 5: Preconditioned iteration, with full diagnostics.  The
+     preconditioner (quite strange, because even the original matrix A
+     is trivial) is defined as a function
+
+          function y = apply_m (x)

+     Produce the incomplete LU factorization of the sparse matrix A.
+     Two types of incomplete factorization are possible, and the type is
+     determined by the second argument to 'luinc'.
+
+     Called with a second argument of '0', the zero-level incomplete
+     LU factorization is produced.  This creates a factorization of A
+     where the position of the non-zero arguments correspond to the same
+     positions as in the matrix A.
+
+     Alternatively, the fill-in of the incomplete LU factorization can
+     be controlled through the variable DROPTOL or the structure OPTS.
+     The UMFPACK multifrontal factorization code by Tim A. Davis is used
+     for the incomplete LU factorization, (availability
+     )
+
+     DROPTOL determines the values below which the values in the LU 
+     factorization are dropped and replaced by zero.  It must be a
+     positive scalar, and any values in the factorization whose absolute
+     value are less than this value are dropped, expect if leaving them
+     increase the sparsity of the matrix.  Setting DROPTOL to zero
+     results in a complete LU factorization which is the default.
+
+     OPTS is a structure containing one or more of the fields
+
+     'droptol'
+          The drop tolerance as above.  If OPTS only contains 'droptol'
+          then this is equivalent to using the variable DROPTOL.
+
+     'milu'
+          A logical variable flagging whether to use the modified
+          incomplete LU  factorization.  In the case that 'milu' is
+          true, the dropped values are subtracted from the diagonal of
+          the matrix U of the factorization.  The default is 'false'.
+
+     'udiag'
+          A logical variable that flags whether zero elements on the
+          diagonal of U should be replaced with DROPTOL to attempt to
+          avoid singular factors.  The default is 'false'.
+
+     'thresh'
+          Defines the pivot threshold in the interval [0,1].  Values
+          outside that range are ignored.
+
+     All other fields in OPTS are ignored.  The outputs from 'luinc' are
+     the same as for 'lu'.
+
+     Given the string argument "vector", 'luinc' returns the values of P
+     Q as vector values.

-32.1 Loading and Saving Images
-==============================
-
-The first step in most image processing tasks is to load an image into
-Octave which is done with the 'imread' function.  The 'imwrite' function
-is the corresponding function for writing images to the disk.
-
-   In summary, most image processing code will follow the structure of
-this code
-
-     I = imread ("my_input_image.img");
-     J = process_my_image (I);
-     imwrite (J, "my_output_image.img");
-
- -- Function File: [IMG, MAP, ALPHA] = imread (FILENAME)
- -- Function File: [...] = imread (FILENAME, EXT)
- -- Function File: [...] = imread (URL)
- -- Function File: [...] = imread (..., IDX)
- -- Function File: [...] = imread (..., PARAM1, VAL1, ...)
-     Read images from various file formats.
-
-     Reads an image as a matrix from the file FILENAME.  If there is no
-     file FILENAME, and EXT was specified, it will look for a file named
-     FILENAME and extension EXT, i.e., a file named FILENAME.EXT.
-
-     The size and class of the output depends on the format of the
-     image.  A color image is returned as an MxNx3 matrix.  Gray-level
-     and black-and-white images are of size MxN. Multipage images will
-     have an additional 4th dimension.
-
-     The bit depth of the image determines the class of the output:
-     "uint8", "uint16" or "single" for gray and color, and "logical" for
-     black and white.  Note that indexed images always return the
-     indexes for a colormap, independent if MAP is a requested output.
-     To obtain the actual RGB image, use 'ind2rgb'.  When more than one
-     indexed image is being read, MAP is obtained from the first.  In
-     some rare cases this may be incorrect and 'imfinfo' can be used to
-     obtain the colormap of each image.
-
-     See the Octave manual for more information in representing images.
-
-     Some file formats, such as TIFF and GIF, are able to store multiple
-     images in a single file.  IDX can be a scalar or vector specifying
-     the index of the images to read.  By default, Octave will only read
-     the first page.
-
-     Depending on the file format, it is possible to configure the
-     reading of images with PARAM, VAL pairs.  The following options are
-     supported:
-
-     '"Frames" or "Index"'
-          This is an alternative method to specify IDX.  When specifying
-          it in this way, its value can also be the string "all".
-
-     '"Info"'
-          This option exists for MATLAB compatibility and has no effect.
-          For maximum performance while reading multiple images from a
-          single file, use the Index option.
-
-     '"PixelRegion"'
-          Controls the image region that is read.  Takes as value a cell
-          array with two arrays of 3 elements '{ROWS COLS}'.  The
-          elements in the array are the start, increment and end pixel
-          to be read.  If the increment value is omitted, defaults to 1.

-     *note imformats: XREFimformats.
-
- -- Function File: imwrite (IMG, FILENAME)
- -- Function File: imwrite (IMG, FILENAME, EXT)
- -- Function File: imwrite (IMG, MAP, FILENAME)
- -- Function File: imwrite (..., PARAM1, VAL1, ...)
-     Write images in various file formats.
-
-     The image IMG can be a binary, grayscale, RGB, or multi-dimensional
-     image.  The size and class of IMG should be the same as what should
-     be expected when reading it with 'imread': the 3rd and 4th
-     dimensions reserved for color space, and multiple pages
-     respectively.  If it's an indexed image, the colormap MAP must also
-     be specified.
-
-     If EXT is not supplied, the file extension of FILENAME is used to
-     determine the format.  The actual supported formats are dependent
-     on options made during the build of Octave.  Use 'imformats' to
-     check the support of the different image formats.
-
-     Depending on the file format, it is possible to configure the
-     writing of images with PARAM, VAL pairs.  The following options are
-     supported:
-
-     'Alpha'
-          Alpha (transparency) channel for the image.  This must be a
-          matrix with same class, and number of rows and columns of IMG.
-          In case of a multipage image, the size of the 4th dimension
-          must also match and the third dimension must be a singleton.
-          By default, image will be completely opaque.
-
-     'DelayTime'
-          For formats that accept animations (such as GIF), controls for
-          how long a frame is displayed until it moves to the next one.
-          The value must be scalar (which will applied to all frames in
-          IMG), or a vector of length equal to the number of frames in
-          IM.  The value is in seconds, must be between 0 and 655.35,
-          and defaults to 0.5.
-
-     'DisposalMethod'
-          For formats that accept animations (such as GIF), controls
-          what happens to a frame before drawing the next one.  Its
-          value can be one of the following strings: "doNotSpecify"
-          (default); "leaveInPlace"; "restoreBG"; and "restorePrevious",
-          or a cell array of those string with length equal to the
-          number of frames in IMG.
-
-     'LoopCount'
-          For formats that accept animations (such as GIF), controls how
-          many times the sequence is repeated.  A value of Inf means an
-          infinite loop (default), a value of 0 or 1 that the sequence
-          is played only once (loops zero times), while a value of 2 or
-          above loops that number of times (looping twice means it plays
-          the complete sequence 3 times).  This option is ignored when
-          there is only a single image at the end of writing the file.
-
-     'Quality'
-          Set the quality of the compression.  The value should be an
-          integer between 0 and 100, with larger values indicating
-          higher visual quality and lower compression.  Defaults to 75.
-
-     'WriteMode'
-          Some file formats, such as TIFF and GIF, are able to store
-          multiple images in a single file.  This option specifies if
-          IMG should be appended to the file (if it exists) or if a new
-          file should be created for it (possibly overwriting an
-          existing file).  The value should be the string "Overwrite"
-          (default), or "Append".
-
-          Despite this option, the most efficient method of writing a
-          multipage image is to pass a 4 dimensional IMG to 'imwrite',
-          the same matrix that could be expected when using 'imread'
-          with the option "Index" set to "all".

-
- -- Built-in Function: VAL = IMAGE_PATH ()
- -- Built-in Function: OLD_VAL = IMAGE_PATH (NEW_VAL)
- -- Built-in Function: IMAGE_PATH (NEW_VAL, "local")
-     Query or set the internal variable that specifies a colon separated
-     list of directories in which to search for image files.
-
-     When called from inside a function with the "local" option, the
-     variable is changed locally for the function and any subroutines it
-     calls.  The original variable value is restored when exiting the
-     function.

-
-   It is possible to get information about an image file on disk,
-without actually reading it into Octave.  This is done using the
-'imfinfo' function which provides read access to many of the parameters
-stored in the header of the image file.
-
- -- Function File: INFO = imfinfo (FILENAME)
- -- Function File: INFO = imfinfo (FILENAME, EXT)
- -- Function File: INFO = imfinfo (URL)
-     Read image information from a file.
-
-     'imfinfo' returns a structure containing information about the
-     image stored in the file FILENAME.  If there is no file FILENAME,
-     and EXT was specified, it will look for a file named FILENAME and
-     extension EXT, i.e., a file named FILENAME.EXT.
-
-     The output structure INFO contains the following fields:
-
-     'Filename'
-          The full name of the image file.
-
-     'FileModDate'

-
-   By default, Octave's image IO functions ('imread', 'imwrite', and
-'imfinfo') use the 'GraphicsMagick' library for their operations.  This
-means a vast number of image formats is supported but considering the
-large amount of image formats in science and its commonly closed nature,
-it is impossible to have a library capable of reading them all.  Because
-of this, the function 'imformats' keeps a configurable list of available
-formats, their extensions, and what functions should the image IO
-functions use.  This allows to expand Octave's image IO capabilities by
-creating functions aimed at acting on specific file formats.
-
-   While it would be possible to call the extra functions directly,
-properly configuring Octave with 'imformats' allows to keep a consistent
-code that is abstracted from file formats.
-
-   It is important to note that a file format is not actually defined by
-its file extension and that 'GraphicsMagick' is capable to read and
-write more file formats than the ones listed by 'imformats'.  What this
-means is that even with an incorrect or missing extension the image may
-still be read correctly, and that even unlisted formats are not
-necessarily unsupported.

-
-     FORMATS is a structure with information about each supported file

-
-     ext

+     be specified.
+
+     If EXT is not supplied, the file extension of FILENAME is used to
+     determine the format.  The actual supported formats are dependent
+     on options made during the build of Octave.  Use 'imformats' to
+     check the support of the different image formats.
+
+     Depending on the file format, it is possible to configure the
+     writing of images with PARAM, VAL pairs.  The following options are
+     supported:
+
+     'Alpha'
+          Alpha (transparency) channel for the image.  This must be a
+          matrix with same class, and number of rows and columns of IMG.
+          In case of a multipage image, the size of the 4th dimension
+          must also match and the third dimension must be a singleton.
+          By default, image will be completely opaque.
+
+     'DelayTime'
+          For formats that accept animations (such as GIF), controls for
+          how long a frame is displayed until it moves to the next one.
+          The value must be scalar (which will applied to all frames in
+          IMG), or a vector of length equal to the number of frames in
+          IM.  The value is in seconds, must be between 0 and 655.35,
+          and defaults to 0.5.
+
+     'DisposalMethod'
+          For formats that accept animations (such as GIF), controls
+          what happens to a frame before drawing the next one.  Its
+          value can be one of the following strings: "doNotSpecify"
+          (default); "leaveInPlace"; "restoreBG"; and "restorePrevious",
+          or a cell array of those string with length equal to the
+          number of frames in IMG.
+
+     'LoopCount'
+          For formats that accept animations (such as GIF), controls how
+          many times the sequence is repeated.  A value of Inf means an
+          infinite loop (default), a value of 0 or 1 that the sequence
+          is played only once (loops zero times), while a value of 2 or
+          above loops that number of times (looping twice means it plays
+          the complete sequence 3 times).  This option is ignored when
+          there is only a single image at the end of writing the file.
+
+     'Quality'
+          Set the quality of the compression.  The value should be an
+          integer between 0 and 100, with larger values indicating
+          higher visual quality and lower compression.  Defaults to 75.
+
+     'WriteMode'
+          Some file formats, such as TIFF and GIF, are able to store
+          multiple images in a single file.  This option specifies if
+          IMG should be appended to the file (if it exists) or if a new
+          file should be created for it (possibly overwriting an
+          existing file).  The value should be the string "Overwrite"
+          (default), or "Append".
+
+          Despite this option, the most efficient method of writing a
+          multipage image is to pass a 4 dimensional IMG to 'imwrite',
+          the same matrix that could be expected when using 'imread'
+          with the option "Index" set to "all".

+
+     'imfinfo' returns a structure containing information about the

+
+   By default, Octave's image IO functions ('imread', 'imwrite', and
+'imfinfo') use the 'GraphicsMagick' library for their operations.  This
+means a vast number of image formats is supported but considering the
+large amount of image formats in science and its commonly closed nature,
+it is impossible to have a library capable of reading them all.  Because
+of this, the function 'imformats' keeps a configurable list of available
+formats, their extensions, and what functions should the image IO
+functions use.  This allows to expand Octave's image IO capabilities by
+creating functions aimed at acting on specific file formats.
+
+   While it would be possible to call the extra functions directly,
+properly configuring Octave with 'imformats' allows to keep a consistent
+code that is abstracted from file formats.
+
+   It is important to note that a file format is not actually defined by
+its file extension and that 'GraphicsMagick' is capable to read and
+write more file formats than the ones listed by 'imformats'.  What this
+means is that even with an incorrect or missing extension the image may
+still be read correctly, and that even unlisted formats are not
+necessarily unsupported.

+
+     FORMATS is a structure with information about each supported file
+     format, or from a specific format EXT, the value displayed on the
+     field 'ext'.  It contains the following fields:
+
+     ext
+          The name of the file format.  This may match the file
+          extension but Octave will automatically detect the file
+          format.
+
+     description
+          A long description of the file format.
+
+     isa
+          A function handle to confirm if a file is of the specified
+          format.

+          A function handle to obtain image information of the specified
+          format.
+
+     alpha
+          Logical value if format supports alpha channel (transparency
+          or matte).
+
+     multipage
+          Logical value if format supports multipage (multiple images
+          per file).
+
+     It is possible to change the way Octave manages file formats with
+     the options "add", "remove", and "update", and supplying a
+     structure FORMAT with the required fields.  The option "factory"
+     resets the configuration to the default.
+
+     This can be used by Octave packages to extend the image reading
+     capabilities Octave, through use of the PKG_ADD and PKG_DEL
+     commands.

-'octave_value' and returning it as an 'octave_value', can be seen in the

-A.1.7 Accessing Global Variables in Oct-Files
----------------------------------------------
-
-Global variables allow variables in the global scope to be accessed.
-Global variables can be accessed within oct-files by using the support
-functions 'get_global_value' and 'set_global_value'.  'get_global_value'
-takes two arguments, the first is a string representing the variable
-name to obtain.  The second argument is a boolean argument specifying
-what to do if no global variable of the desired name is found.  An
-example of the use of these two functions is
-
-     #include 
-
-     DEFUN_DLD (globaldemo, args, , "Global Demo")
-     {
-       octave_value retval;
-       int nargin = args.length ();
-
-       if (nargin != 1)
-         print_usage ();
-       else
-         {
-           std::string s = args(0).string_value ();
-           if (! error_state)
-             {
-               octave_value tmp = get_global_value (s, true);
-               if (tmp.is_defined ())
-                 retval = tmp;
-               else
-                 retval = "Global variable not found";
-
-               set_global_value ("a", 42.0);
-             }
-         }
-       return retval;
-     }
-
-
-   An example of its use is
-
-     global a b
-     b = 10;
-     globaldemo ("b")
-     => 10
-     globaldemo ("c")
-     => "Global variable not found"
-     num2str (a)

-A.1.8 Calling Octave Functions from Oct-Files
----------------------------------------------
-
-There is often a need to be able to call another Octave function from
-within an oct-file, and there are many examples of such within Octave
-itself.  For example, the 'quad' function is an oct-file that calculates
-the definite integral by quadrature over a user supplied function.
-
-   There are also many ways in which a function might be passed.  It
-might be passed as one of
-
-  1. Function Handle
-
-  2. Anonymous Function Handle
-
-  3. Inline Function
-
-  4. String
-
-   The example below demonstrates an example that accepts all four means
-of passing a function to an oct-file.
-
-     #include 
-     #include 
-
-     DEFUN_DLD (funcdemo, args, nargout, "Function Demo")
-     {
-       octave_value_list retval;
-       int nargin = args.length ();
-
-       if (nargin < 2)
-         print_usage ();
-       else
-         {
-           octave_value_list newargs;
-           for (octave_idx_type i = nargin - 1; i > 0; i--)
-             newargs(i-1) = args(i);
-           if (args(0).is_function_handle () || args(0).is_inline_function ())
-             {
-               octave_function *fcn = args(0).function_value ();
-               if (! error_state)
-                 retval = feval (fcn, newargs, nargout);
-             }
-           else if (args(0).is_string ())
-             {
-               std::string fcn = args(0).string_value ();
-               if (! error_state)
-                 retval = feval (fcn, newargs, nargout);
-             }
-           else
-             error ("funcdemo: INPUT must be string, inline, or function handle");
-         }
-       return retval;
-     }
-
-
-   The first argument to this demonstration is the user-supplied
-function and the remaining arguments are all passed to the user
-function.
-
-     funcdemo (@sin,1)
-     => 0.84147
-     funcdemo (@(x) sin (x), 1)
-     => 0.84147
-     funcdemo (inline ("sin (x)"), 1)
-     => 0.84147
-     funcdemo ("sin",1)
-     => 0.84147
-     funcdemo (@atan2, 1, 1)
-     => 0.78540
-
-   When the user function is passed as a string the treatment of the
-function is different.  In some cases it is necessary to have the user
-supplied function as an 'octave_function' object.  In that case the
-string argument can be used to create a temporary function as
-demonstrated below.
-
-     std::octave fcn_name = unique_symbol_name ("__fcn__");
-     std::string fcode = "function y = ";
-     fcode.append (fcn_name);
-     fcode.append ("(x) y = ");
-     fcn = extract_function (args(0), "funcdemo", fcn_name,
-                             fcode, "; endfunction");
-     ...
-     if (fcn_name.length ())
-       clear_function (fcn_name);
-
-   There are two important things to know in this case.  First, the
-number of input arguments to the user function is fixed, and in the
-above example is a single argument.  Second, to avoid leaving the
-temporary function in the Octave symbol table it should be cleared after
-use.  Also, by convention internal function names begin and end with the
-character sequence '__'.

-A.1.9 Calling External Code from Oct-Files
-------------------------------------------
-
-Linking external C code to Octave is relatively simple, as the C
-functions can easily be called directly from C++.  One possible issue is
-that the declarations of the external C functions may need to be
-explicitly defined as C functions to the compiler.  If the declarations
-of the external C functions are in the header 'foo.h', then the tactic
-to ensure that the C++ compiler treats these declarations as C code is
-
-     #ifdef __cplusplus
-     extern "C"
-     {
-     #endif
-     #include "foo.h"
-     #ifdef __cplusplus
-     }  /* end extern "C" */
-     #endif
-
-   Calling Fortran code, however, can pose more difficulties.  This is
-due to differences in the manner in which compilers treat the linking of
-Fortran code with C or C++ code.  Octave supplies a number of macros
-that allow consistent behavior across a number of compilers.
-
-   The underlying Fortran code should use the 'XSTOPX' function to
-replace the Fortran 'STOP' function.  'XSTOPX' uses the Octave exception
-handler to treat failing cases in the Fortran code explicitly.  Note
-that Octave supplies its own replacement BLAS 'XERBLA' function, which
-uses 'XSTOPX'.
-
-   If the code calls 'XSTOPX', then the 'F77_XFCN' macro should be used
-to call the underlying Fortran function.  The Fortran exception state
-can then be checked with the global variable
-'f77_exception_encountered'.  If 'XSTOPX' will not be called, then the 'F77_FCN'
-macro should be used instead to call the Fortran code.
-
-   There is no great harm in using 'F77_XFCN' in all cases, except that
-for Fortran code that is short running and executes a large number of
-times, there is potentially an overhead in doing so.  However, if 'F77_FCN'
-is used with code that calls 'XSTOP', Octave can generate a segmentation
-fault.
-
-   An example of the inclusion of a Fortran function in an oct-file is
-given in the following example, where the C++ wrapper is
-
-     #include 
-     #include 
-
-     extern "C"
-     {
-       F77_RET_T
-       F77_FUNC (fortsub, FORTSUB)
-         (const int&, double*, F77_CHAR_ARG_DECL F77_CHAR_ARG_LEN_DECL);
-     }
-
-     DEFUN_DLD (fortdemo, args, , "Fortran Demo")
-     {
-       octave_value_list retval;
-       int nargin = args.length ();
-
-       if (nargin != 1)
-         print_usage ();
-       else
-         {
-           NDArray a = args(0).array_value ();
-           if (! error_state)
-             {
-               double *av = a.fortran_vec ();
-               octave_idx_type na = a.numel ();
-               OCTAVE_LOCAL_BUFFER (char, ctmp, 128);
-
-               F77_XFCN (fortsub, FORTSUB,
-                         (na, av, ctmp F77_CHAR_ARG_LEN (128)));
-
-               retval(1) = std::string (ctmp);
-               retval(0) = a;
-             }
-         }
-       return retval;
-     }
-
-
-and the Fortran function is
-
-           subroutine fortsub (n, a, s)
-           implicit none
-           character*(*) s
-           real*8 a(*)
-           integer*4 i, n, ioerr
-           do i = 1, n
-             if (a(i) .eq. 0d0) then
-               call xstopx ('fortsub: divide by zero')
-             else
-               a(i) = 1d0 / a(i)
-             endif
-           enddo
-           write (unit = s, fmt = '(a,i3,a,a)', iostat = ioerr)
-          $       'There are ', n,
-          $       ' values in the input vector', char(0)
-           if (ioerr .ne. 0) then
-             call xstopx ('fortsub: error writing string')
-           endif
-           return
-           end
-
-
-
-   This example demonstrates most of the features needed to link to an
-external Fortran function, including passing arrays and strings, as well
-as exception handling.  Both the Fortran and C++ files need to be
-compiled in order for the example to work.

+can then be checked with the global variable
+'f77_exception_encountered'.  If 'XSTOPX' will not be called, then the 'F77_FCN'
+macro should be used instead to call the Fortran code.
+
+   There is no great harm in using 'F77_XFCN' in all cases, except that
+for Fortran code that is short running and executes a large number of
+times, there is potentially an overhead in doing so.  However, if 'F77_FCN'
+is used with code that calls 'XSTOP', Octave can generate a segmentation
+fault.

+        <p><strong>A Note about Octave's New GUI</strong></p><p>One of the biggest new features for Octave 3.8 is a graphical user interface.  It is the one thing that users have requested most often over the last few years and now it is almost ready.  But because it is not quite as polished as we would like, we have decided to wait until the 4.0.x release series before making the GUI the default interface.</p><p>Given the length of time and the number of bug fixes and improvements since the last major release, we also decided against delaying the release of all these new improvements any longer just to perfect the GUI.  So please enjoy the 3.8 release of Octave and the preview of the new GUI.  We believe it is working reasonably well, but we also know that there are some obvious rough spots and many things that could be improved.</p><p><strong>We Need Your Help</strong></p><p>There are many ways that you can help us fix the remaining problems, complete the GUI, and improve the overall user experience for both novices and experts alike (links will open an external browser):</p><p><ul><li>If you are a skilled software developer, you can help by contributing your time to help <a href="http://octave.org/get-involved.html">develop Octave</a>.</li><li>If Octave does not work properly, you are encouraged to <a href="http://octave.org/bugs.html">report problems </a> that you find.</li><li>Whether you are a user or developer, you can <a href="http://octave.org/donate.html">help to fund the project</a>.  Octave development takes a lot of time and expertise.  Your contributions help to ensure that Octave will continue to improve.</li></ul></p><p>We hope you find Octave to be useful.  Please help us make it even better for the future!</p>
+        <p><strong>Нататка пра новы GUI Octave</strong></p><p>Адна з найбольшых адметнасцяў Octave 3.8 - графічны інтэрфэйс.  Карыстальнікі апошнімі гадамі прасілі яго найбольш часта, і нарэшце ён амаль гатовы.  Але ён пакуль не такі дасканалы, як бы мы жадалі, таму мы вырашылі пачакаць выпуску з серыі 4.0.x перад тым, як рабіць яго стандартным.</p><p>Да таго ж, улічваючы час і колькасць выпраўленняў і паляпшэнняў у параўнанні з апошнім буйным выпускам Octave, мы вырашылі затрымліваць новы выпуск толькі дзеля ўдасканалення GUI, не зважаючы на новыя магчымасці.  Таму прыемнага вам карстання выпускам 3.8 і першай версіяй новага інтэрфэйсу.  Нам здаецца, ён працуе даволі добра, але мы ведаем, што ёсць некаторыя відавочныя грубыя недарэчнасці і шмат чаго, што можна палепшыць.</p><p><strong>Нам патрабуецца ваша дапамога</strong></p><p>Ёсць шмат спосабаў, якімі вы можаце дапамагчы нам выправіць праблемы, што яшчэ засталіся, скончыць GUI і палепшыць агульнае уражанне як для новых карыстальнікаў, так і для экспертаў (спасылкі адкрыюцца ў знешнім браўзэры):</p><p><ul><li>Калі вы спрактыкаваны распрацоўнік праграм, то можаце выдаткаваць час, каб дапамагчы ў <a href="http://octave.org/get-involved.html">распрацоўцы Octave</a>.</li><li>Калі Octave працуе з памылкамі, вы можаце <a href="http://octave.org/bugs.html">паведаміць пра праблемы</a>, з якімі сутыкнуліся.</li><li>Няхай вы хоць карыстальнік, хоць распрацоўнік, вы можаце <a href="http://octave.org/donate.html">прафундаваць праект</a>.  Распрацоўка Octave патрабуе шмат часу і навыкаў.  Ваш удзел дапаможа гарантаваць, што Octave і надалей будзе ўдасканальвацца.</li></ul></p><p>Спадзяемся, вы знойдзеце Octave карыснай.  Калі ласка, дапамажыце нам зрабіць яго лепшым для будучыні!</p>

-        <p><strong>Нататка пра новы GUI Octave</strong></p><p>Адна з найбольшых адметнасцяў Octave 3.8 - графічны інтэрфэйс.  Карыстальнікі апошнімі гадамі прасілі яго найбольш часта, і нарэшце ён амаль гатовы.  Але ён пакуль не такі дасканалы, як бы мы жадалі, таму мы вырашылі пачакаць выпуску з серыі 4.0.x перад тым, як рабіць яго стандартным.</p><p>Да таго ж, улічваючы час і колькасць выпраўленняў і паляпшэнняў у параўнанні з апошнім буйным выпускам Octave, мы вырашылі затрымліваць новы выпуск толькі дзеля ўдасканалення GUI, не зважаючы на новыя магчымасці.  Таму прыемнага вам карстання выпускам 3.8 і першай версіяй новага інтэрфэйсу.  Нам здаецца, ён працуе даволі добра, але мы ведаем, што ёсць некаторыя відавочныя грубыя недарэчнасці і шмат чаго, што можна палепшыць.</p><p><strong>Нам патрабуецца ваша дапамога</strong></p><p>Ёсць шмат спосабаў, якімі вы можаце дапамагчы нам выправіць праблемы, што яшчэ засталіся, скончыць GUI і палепшыць агульнае уражанне як для новых карыстальнікаў, так і для экспертаў (спасылкі адкрыюцца ў знешнім браўзэры):</p><p><ul><li>Калі вы спрактыкаваны распрацоўнік праграм, то можаце выдаткаваць час, каб дапамагчы ў <a href="http://octave.org/get-involved.html">распрацоўцы Octave</a>.</li><li>Калі Octave працуе з памылкамі, вы можаце <a href="http://octave.org/bugs.html">паведаміць пра праблемы</a>, з якімі сутыкнуліся.</li><li>Няхай вы хоць карыстальнік, хоць распрацоўнік, вы можаце <a href="http://octave.org/donate.html">прафундаваць праект</a>.  Распрацоўка Octave патрабуе шмат часу і навыкаў.  Ваш удзел дапаможа гарантаваць, што Octave і надалей будзе ўдасканальвацца.</li></ul></p><p>Спадзяемся, вы знойдзеце Octave карыснай.  Калі ласка, дапамажыце нам зрабіць яго лепшым для будучыні!</p>

-        <p><strong>Einige Hinweise zur neuen Octave GUI</strong></p><p>Eine der größten Neuerungen von Octave 3.8 ist die grafische Benutzerschnittstelle (GUI).  Sie ist das, worum die Nutzer in den letzten Jahren am häufigsten gebeten haben, und nun ist sie fast fertig.  Aber weil noch der Feinschliff fehlt, haben wir beschlossen, mit der GUI als Standard-Benutzerschnittstelle auf die 4.0.x Veröffentlichungen zu warten.</p><p>In Anbetracht der vergangenen Zeit, der Anzahl der behobenen Fehler und den Verbesserungen seit der letzten Veröffentlichung haben wir uns dazu entschieden, die nächste Veröffentlichung nicht weiter zu verzögern, nur um die GUI zu perfektionieren.  Daher wünschen wir viel Spaß mit der Version 3.8 von Octave und der Vorschau auf die neue GUI.  Wir sind der Meinung, dass sie schon ziemlich gut funktioniert, obwohl uns bewusst ist, dass es noch einige Ecken und Kanten sowie viele Dinge zu verbessern gibt.</p><p><strong>Deshalb brauchen wir Deine Mithilfe!</strong></p><p>Es gibt viele Möglichkeiten uns zu helfen die verbleibenden Probleme zu beheben, die GUI weiter zu entwickeln und die Benutzererfahrung für Neulinge und Experten gleichermaßen zu verbessern (Links öffnen im externen Browser):</p><p><ul><li>Falls Du ein geschickter Software-Entwickler bist, kannst du helfen, indem du dich an der <a href="http://octave.org/get-involved.html">Weiterentwicklung von Octave</a> beteiligst.</li><li>Sollte Octave einmal nicht wie erwartet funktionieren, solltest Du das gefundene <a href="http://octave.org/bugs.html">Problem melden</a>.</li><li>Egal, ob Du Anwender oder Entwickler bist, kannst du <a href="http://octave.org/donate.html">helfen, das Projekt zu finanzieren</a>.  Die Weiterentwicklung von Octave braucht viel Zeit und Sachverstand.  Dein Beitrag hilft sicherzustellen, dass Octave weiter verbessert wird.</li></ul></p><p>Wir hoffen, dass du Octave nützlich findest.  Bitte hilf uns Octave zukünftig noch besser zu machen!</p>

+        <p><strong>Nota acerca de la nueva GUI de Octave</strong></p><p>Una de las novedades más grandes de Octave 3.8 es la interfaz gráfica de usuario.  Esto ha sido algo que los usuarios han solicitado frecuentemente durante los últimos años, y ahora está casi lista. Pero como esta interfaz aún no está tan pulida como a nosotros nos gustaría, hemos decidido esperar hasta la serie de versiones 4.0.x de Octave para hacer a la GUI la interfaz por defecto.</p><p>Dado el tiempo transcurrido, el número de correcciones de errores del software (bugs) y el número de mejoras desde la última versión mayor de Octave, también hemos decidido retrasar el lanzamiento de todas estas nuevas mejoras durante más tiempo con el fin de perfeccionar la GUI.  Disfrute de la versión 3.8 de Octave y la versión previa de la nueva GUI.  Creemos que está funcionando razonablemente bien, pero también somos conscientes de que existen muchas cosas que se pueden mejorar.</p><p><strong>Necesitamos su ayuda</strong></p><p>Hay varias maneras mediante las cuales usted nos puede ayudar a arreglar errores, completar la GUI y, en general, mejorar la experiencia del usuario, ya sean novatos o expertos (los enlaces se abrirán en un navegador externo):</p><p><ul><li>Si usted es un desarrollador de software experimentado, puede contribuir con su tiempo para ayudar <a href="http://octave.org/get-involved.html">Desarrollo de Octave</a>.</li><li>Si Octave no funciona adecuadamente, se le invita a  <a href="http://octave.org/bugs.html">reportar problemas </a> que haya encontrado.</li><li>Si usted es usuario o desarrollador, puede <a href="http://octave.org/donate.html">ayudar a financiar el proyecto</a>.  El desarrollo de Octave necesita tiempo y conocimientos. Su contribución ayudaría en gran medida a asegurar que Octave continúe mejorando.</li></ul></p><p>Esperamos que haya encontrado Octave muy útil.

-        <p><strong>A Note about Octave's New GUI</strong></p><p>One of the biggest new features for Octave 3.8 is a graphical user interface.  It is the one thing that users have requested most often over the last few years and now it is almost ready.  But because it is not quite as polished as we would like, we have decided to wait until the 4.0.x release series before making the GUI the default interface.</p><p>Given the length of time and the number of bug fixes and improvements since the last major release Octave, we also decided against delaying the release of all these new improvements any longer just to perfect the GUI.  So please enjoy the 3.8 release of Octave and the preview of the new GUI.  We believe it is working reasonably well, but we also know that there are some obvious rough spots and many things that could be improved.</p><p><strong>We Need Your Help</strong></p><p>There are many ways that you can help us fix the remaining problems, complete the GUI, and improve the overall user experience for both novices and experts alike (links will open an external browser):</p><p><ul><li>If you are a skilled software developer, you can help by contributing your time to help <a href="http://octave.org/get-involved.html">develop Octave</a>.</li><li>If Octave does not work properly, you are encouraged to <a href="http://octave.org/bugs.html">report problems </a> that you find.</li><li>Whether you are a user or developer, you can <a href="http://octave.org/donate.html">help to fund the project</a>.  Octave development takes a lot of time and expertise.  Your contributions help to ensure that Octave will continue to improve.</li></ul></p><p>We hope you find Octave to be useful.  Please help us make it even better for the future!</p>
-        <p><strong>Nota acerca de la nueva GUI de Octave</strong></p><p>Una de las novedades más grandes de Octave 3.8 es la interfaz gráfica de usuario.  Esto ha sido algo que los usuarios han solicitado frecuentemente durante los últimos años, y ahora está casi lista. Pero como esta interfaz aún no está tan pulida como a nosotros nos gustaría, hemos decidido esperar hasta la serie de versiones 4.0.x de Octave para hacer a la GUI la interfaz por defecto.</p><p>Dado el tiempo transcurrido, el número de correcciones de errores del software (bugs) y el número de mejoras desde la última versión mayor de Octave, también hemos decidido retrasar el lanzamiento de todas estas nuevas mejoras durante más tiempo con el fin de perfeccionar la GUI.  Disfrute de la versión 3.8 de Octave y la versión previa de la nueva GUI.  Creemos que está funcionando razonablemente bien, pero también somos conscientes de que existen muchas cosas que se pueden mejorar.</p><p><strong>Necesitamos su ayuda</strong></p><p>Hay varias maneras mediante las cuales usted nos puede ayudar a arreglar errores, completar la GUI y, en general, mejorar la experiencia del usuario, ya sean novatos o expertos (los enlaces se abrirán en un navegador externo):</p><p><ul><li>Si usted es un desarrollador de software experimentado, puede contribuir con su tiempo para ayudar <a href="http://octave.org/get-involved.html">Desarrollo de Octave</a>.</li><li>Si Octave no funciona adecuadamente, se le invita a  <a href="http://octave.org/bugs.html">reportar problemas </a> que haya encontrado.</li><li>Si usted es usuario o desarrollador, puede <a href="http://octave.org/donate.html">ayudar a financiar el proyecto</a>.

+        <p><strong>A Note about Octave's New GUI</strong></p><p>One of the biggest new features for Octave 3.8 is a graphical user interface.  It is the one thing that users have requested most often over the last few years and now it is almost ready.  But because it is not quite as polished as we would like, we have decided to wait until the 4.0.x release series before making the GUI the default interface.</p><p>Given the length of time and the number of bug fixes and improvements since the last major release, we also decided against delaying the release of all these new improvements any longer just to perfect the GUI.  So please enjoy the 3.8 release of Octave and the preview of the new GUI.  We believe it is working reasonably well, but we also know that there are some obvious rough spots and many things that could be improved.</p><p><strong>We Need Your Help</strong></p><p>There are many ways that you can help us fix the remaining problems, complete the GUI, and improve the overall user experience for both novices and experts alike (links will open an external browser):</p><p><ul><li>If you are a skilled software developer, you can help by contributing your time to help <a href="http://octave.org/get-involved.html">develop Octave</a>.</li><li>If Octave does not work properly, you are encouraged to <a href="http://octave.org/bugs.html">report problems </a> that you find.</li><li>Whether you are a user or developer, you can <a href="http://octave.org/donate.html">help to fund the project</a>.  Octave development takes a lot of time and expertise.  Your contributions help to ensure that Octave will continue to improve.</li></ul></p><p>We hope you find Octave to be useful.  Please help us make it even better for the future!</p>

C'est bien la fonctionnalité que les utilisateurs ont le plus réclamée durant les dernières années, et elle est maintenant presque prête. Elle n'est pas aussi parfaite que nous le souhaiterions et c'est pourquoi nous avons décidé d'attendre la version 4.0 pour en faire l'interface par défaut.</p><p>Au vu du nombre de bug résolus et des améliorations apportées depuis la dernière version majeure d'Octave, nous avons décidé  de ne pas retarder plus la parution de ces améliorations pour perfectionner le GUI. Vous pouvez maintenant apprécier la version 3.8 et la version préliminaire de la nouvelle interface graphique. Nous pensons qu'elle fonctionne raisonnablement bien, mais nous savons aussi qu'il y a des points durs évidents et beaucoup d'améliorations possibles.</p><p><strong>Nous avons besoin de votre aide</strong></p><p>Il y a de multiples manières d'aider à résoudre les bogues restants, à terminer le GUI et à améliorer l'expérience utilisateur aussi bien pour les novices que pour les experts (liens ouverts dans un navigateur externe):</p><p><ul><li>Si vous êtes un développeur  expérimenté, vous pouvez donner de votre temps et <a href="http://octave.org/get-involved.html">développer Octave</a>.</li><li>Si Octave ne fonctionne pas correctement, vous êtes encouragés à <a href="http://octave.org/bugs.html">signaler les problèmes </a> que vous trouvez.</li><li>Que vous soyez utilisateur ou développeur, vous pouvez <a href="http://octave.org/donate.html">aider à financer le projet</a>.

-        <p><strong>Note à propos du nouveau GUI d'Octave</strong></p><p>Parmi les nouvelles fonctionnalités d'Ocatve 3.8, l'interface graphique est une grande évolution. C'est bien la fonctionnalité que les utilisateurs ont le plus réclamée durant les dernières années, et elle est maintenant presque prête. Elle n'est pas aussi parfaite que nous le souhaiterions et c'est pourquoi nous avons décidé d'attendre la version 4.0 pour en faire l'interface par défaut.</p><p>Au vu du nombre de bug résolus et des améliorations apportées depuis la dernière version majeure d'Octave, nous avons décidé  de ne pas retarder plus la parution de ces améliorations pour perfectionner le GUI. Vous pouvez maintenant apprécier la version 3.8 et la version préliminaire de la nouvelle interface graphique. Nous pensons qu'elle fonctionne raisonnablement bien, mais nous savons aussi qu'il y a des points durs évidents et beaucoup d'améliorations possibles.</p><p><strong>Nous avons besoin de votre aide</strong></p><p>Il y a de multiples manières d'aider à résoudre les bogues restants, à terminer le GUI et à améliorer l'expérience utilisateur aussi bien pour les novices que pour les experts (liens ouverts dans un navigateur externe):</p><p><ul><li>Si vous êtes un développeur  expérimenté, vous pouvez donner de votre temps et <a href="http://octave.org/get-involved.html">développer Octave</a>.</li><li>Si Octave ne fonctionne pas correctement, vous êtes encouragés à <a href="http://octave.org/bugs.html">signaler les problèmes </a> que vous trouvez.</li><li>Que vous soyez utilisateur ou développeur, vous pouvez <a href="http://octave.org/donate.html">aider à financer le projet</a>. Le développement d'Octave demande beaucoup de temps et d’expertise. Vos contributions permettent d'assurer qu'Octave continuera à s'améliorer.</li></ul></p><p>Nous espérons que vous trouverez Octave utile. S'il vous plaît, aidez nous à l'améliorer encore dans le futur !</p>

+        <p><strong>Een opmerking over Octave's Nieuwe GUI</strong></p><p>Een van de belangrijkste nieuwe kenmerken van Octave 3.8 is een grafische user interface (GUI).  Dat is waar de gebruikers de afgelopen jaren het meest om gevraagd hebben en hij is bijna af.  Maar omdat hij nog niet zo gepolijst is als we zouden willen hebben we besloten te wachten tot de versie 4.0 serie voordat we hem de standaard interface maken.</p><p>Vanwege de lange tijd en het aantal bug fixes en verbeteringen sinds de laatste major release versie hebben we ook besloten om niet langer meer te wachten op de GUI om al die verbeteringen door te voeren.  Dus geniet van Octave versie 3.8 en de preview van de nieuwe GUI.  We denken dat hij redelijk goed werkt, maar natuurlijk weten we dat er nog ruwe kantjes aan zitten en ruimte voor verbeteringen.</p><p><strong>We hebben je hulp nodig</strong></p><p>Er zijn veel manieren waarop je ons kunt helpen de overgebleven problemen te verhelpen, de GUI te completeren, en de gebruikerservaring voor nieuwelingen en experts (de URLs openen een nieuwe browser):</p><p><ul><li>Als je een bekwame ontwikkelaar bent kun je ons helpen door bij te dragen <a href="http://octave.org/get-involved.html">develop Octave</a>.</li><li>Als Octave niet goed wekt raden we je aan om <a href="http://octave.org/bugs.html">de problemen te rapporteren </a> die je tegen komt.</li><li>Of je nu gebruiker of ontwikkelaar bent, je kunt ook <a href="http://octave.org/donate.html">een bijdrage geven</a>.  De ontwikkeling van Octave vraagt een hoop tijd en expertise.  Je bijdrage helpt er aan mee dat Octave verbeterd blijft worden.</li></ul></p><p>We hopen dat je Octave nuttig vindt.  Help alsjeblieft om het in de toekomst nog beter te maken!</p>

-        <p><strong>Een opmerking over Octave's Nieuwe GUI</strong></p><p>Een van de belangrijkste nieuwe kenmerken van Octave 3.8 is een grafische user interface (GUI).  Dat is waar de gebruikers de afgelopen jaren het meest om gevraagd hebben en hij is bijna af.  Maar omdat hij nog niet zo gepolijst is als we zouden willen hebben we besloten te wachten tot de versie 4.0 serie voordat we hem de standaard interface maken.</p><p>Vanwege de lange tijd en het aantal bug fixes en verbeteringen sinds de laatste major release versie hebben we ook besloten om niet langer meer te wachten op de GUI om al die verbeteringen door te voeren.  Dus geniet van Octave versie 3.8 en de preview van de nieuwe GUI.  We denken dat hij redelijk goed werkt, maar natuurlijk weten we dat er nog ruwe kantjes aan zitten en ruimte voor verbeteringen.</p><p><strong>We hebben je hulp nodig</strong></p><p>Er zijn veel manieren waarop je ons kunt helpen de overgebleven problemen te verhelpen, de GUI te completeren, en de gebruikerservaring voor nieuwelingen en experts (de URLs openen een nieuwe browser):</p><p><ul><li>Als je een bekwame ontwikkelaar bent kun je ons helpen door bij te dragen <a href="http://octave.org/get-involved.html">develop Octave</a>.</li><li>Als Octave niet goed wekt raden we je aan om <a href="http://octave.org/bugs.html">de problemen te rapporteren </a> die je tegen komt.</li><li>Of je nu gebruiker of ontwikkelaar bent, je kunt ook <a href="http://octave.org/donate.html">een bijdrage geven</a>.  De ontwikkeling van Octave vraagt een hoop tijd en expertise.  Je bijdrage helpt er aan mee dat Octave verbeterd blijft worden.</li></ul></p><p>We hopen dat je Octave nuttig vindt.  Help alsjeblieft om het in de toekomst nog beter te maken!</p>

+        <p><strong>Um aviso sobre a nova interface gráfica do Octave</strong></p><p>Uma das funcionalidades novas mais importantes no Octave versão 3.8 é a interface gráfica (GUI).  É uma coisa que os usuários solicitaram muito frequentemente nos últimos anos, e agora ela está quase pronta.  Mas como ela não está tão bem acabada quanto gostaríamos, decidimos esperar até a próxima versão 4.0 antes de tornar a GUI a interface padrão.</p><p>Dado o tempo transcorrido e o número de correções e melhorias desde a última versão, também decidimos não adiar mais o lançamento de todas essas novidades, ao invés ficar aperfeiçoando a GUI.  Portanto, aproveite a versão 3.8 do Octave e a prévia da nova GUI!  Acreditamos que ela está funcionando razoavelmente bem, apesar de alguns aspectos obviamente inacabados, além de muitas melhorias possíveis.</p><p><strong>Ajude-nos</strong></p><p>Há muitas formas de você nos ajudar a corrigir os problemas que persistirem, a finalizar a GUI e a melhorar a usabilidade do Octave em geral, tanto para usuários iniciantes quanto para aqueles mais experientes (os links abaixo serão abertos no seu navegador padrão do sistema; o conteúdo poderá estar em inglês):</p><p><ul><li>Se você for um desenvolvedor de software talentoso, ajude-nos contribuindo com o seu tempo, auxiliando no <a href="http://octave.org/get-involved.html">desenvolvimento do Octave</a>.</li><li>Se o Octave não estiver funcionando corretamente, convidamos-lhe a <a href="http://octave.org/bugs.html">relatar os problemas</a> que você vier a encontrar.</li><li>Quer você seja um usuário ou um desenvolvedor, você poderia <a href="http://octave.org/donate.html">fazer uma doação</a> para auxiliar no financiamento do projeto.  Afinal, o desenvolvimento do Octave demanda tempo e conhecimento consideráveis.  A sua generosidade contribui para assegurar a melhoria contínua do Octave.</li></ul></p><p>Esperamos que você goste do Octave.  Ajude-nos a torná-lo ainda melhor no futuro!</p>

-        <p><strong>A Note about Octave's New GUI</strong></p><p>One of the biggest new features for Octave 3.8 is a graphical user interface.  It is the one thing that users have requested most often over the last few years and now it is almost ready.  But because it is not quite as polished as we would like, we have decided to wait until the 4.0.x release series before making the GUI the default interface.</p><p>Given the length of time and the number of bug fixes and improvements since the last major release Octave, we also decided against delaying the release of all these new improvements any longer just to perfect the GUI.  So please enjoy the 3.8 release of Octave and the preview of the new GUI.  We believe it is working reasonably well, but we also know that there are some obvious rough spots and many things that could be improved.</p><p><strong>We Need Your Help</strong></p><p>There are many ways that you can help us fix the remaining problems, complete the GUI, and improve the overall user experience for both novices and experts alike (links will open an external browser):</p><p><ul><li>If you are a skilled software developer, you can help by contributing your time to help <a href="http://octave.org/get-involved.html">develop Octave</a>.</li><li>If Octave does not work properly, you are encouraged to <a href="http://octave.org/bugs.html">report problems </a> that you find.</li><li>Whether you are a user or developer, you can <a href="http://octave.org/donate.html">help to fund the project</a>.  Octave development takes a lot of time and expertise.  Your contributions help to ensure that Octave will continue to improve.</li></ul></p><p>We hope you find Octave to be useful.  Please help us make it even better for the future!</p>
-        <p><strong>Um aviso sobre a nova interface gráfica do Octave</strong></p><p>Uma das funcionalidades novas mais importantes no Octave versão 3.8 é a interface gráfica (GUI).  É uma coisa que os usuários solicitaram muito frequentemente durante os últimos anos, e agora ela está quase pronta.  Mas como ela não está tão bem acabada quanto gostaríamos, decidimos esperar até a próxima versão 4.0 antes de tornar a GUI a interface padrão do Octave.</p><p>Dado o tempo transcorrido e o número de correções e melhorias desde a última versão do Octave, também decidimos não adiar mais o lançamento de todas essas novidades, ao invés ficar aperfeiçoando a GUI.  Portanto, aproveite a versão 3.8 do Octave e a prévia da nova GUI!  Acreditamos que ela está funcionando razoavelmente bem, apesar de alguns aspectos obviamente inacabados, além de muitas melhorias possíveis.</p><p><strong>Ajude-nos</strong></p><p>Há muitas formas de você nos ajudar a corrigir os problemas que persistirem, a finalizar a GUI e a melhorar a usabilidade do Octave em geral, tanto para usuários iniciantes quanto experientes (os links abaixo serão abertos no seu navegador do sistema; o conteúdo poderá estar em inglês):</p><p><ul><li>Se você for um desenvolvedor de software habilidoso, ajude-nos contribuindo com seu tempo, auxiliando no <a href="http://octave.org/get-involved.html">desenvolvimento do Octave</a>.</li><li>Se o Octave não estiver funcionando corretamente, convidamos-lhe a <a href="http://octave.org/bugs.html">relatar os problemas</a> que vier a encontrar.</li><li>Quer você seja um usuário ou um desenvolvedor, você poderia <a href="http://octave.org/donate.html">fazer uma doação</a> para auxiliar no financiamento do projeto.  Afinal, o desenvolvimento do Octave demanda tempo e conhecimento consideráveis.  A sua generosidade contribui para assegurar que o Octave continuará a ser melhorado.</li></ul></p><p>Esperamos que você goste do Octave.  Ajude-nos a torná-lo ainda melhor no seu futuro!</p>

-        <p><strong>A Note about Octave's New GUI</strong></p><p>One of the biggest new features for Octave 3.8 is a graphical user interface.  It is the one thing that users have requested most often over the last few years and now it is almost ready.  But because it is not quite as polished as we would like, we have decided to wait until the 4.0.x release series before making the GUI the default interface.</p><p>Given the length of time and the number of bug fixes and improvements since the last major release Octave, we also decided against delaying the release of all these new improvements any longer just to perfect the GUI.  So please enjoy the 3.8 release of Octave and the preview of the new GUI.  We believe it is working reasonably well, but we also know that there are some obvious rough spots and many things that could be improved.</p><p><strong>We Need Your Help</strong></p><p>There are many ways that you can help us fix the remaining problems, complete the GUI, and improve the overall user experience for both novices and experts alike (links will open an external browser):</p><p><ul><li>If you are a skilled software developer, you can help by contributing your time to help <a href="http://octave.org/get-involved.html">develop Octave</a>.</li><li>If Octave does not work properly, you are encouraged to <a href="http://octave.org/bugs.html">report problems </a> that you find.</li><li>Whether you are a user or developer, you can <a href="http://octave.org/donate.html">help to fund the project</a>.  Octave development takes a lot of time and expertise.  Your contributions help to ensure that Octave will continue to improve.</li></ul></p><p>We hope you find Octave to be useful.  Please help us make it even better for the future!</p>
