Binary package “libfftw3-double3” in ubuntu trusty

Library for computing Fast Fourier Transforms - Double precision

 The FFTW library computes Fast Fourier Transforms (FFT) in one or more
 dimensions. It is extremely fast. This package contains the shared library
 for double precision transforms.
 To get the static library and the header files, you need to install
 libfftw3-dev. For documentation, see libfftw3-doc.
