Numarray is a set of extensions to the Python programming language
which allows Python programmers to efficiently manipulate large sets
of objects organized in grid-like fashion. These sets of objects are
called arrays, and they can have any number of dimensions.

This is a reimplementation of the earlier Numeric module (aka
numpy). For the most part, the syntax of numarray is identical to
that of Numeric, although there are significant differences. The
differences are primarily in new features.
