$PKGNAME: FFTW (Fastest Fourier Transform in the West)
$PKGNAME:
$PKGNAME: FFTW is a C subroutine library for computing the discrete Fourier
$PKGNAME: transform (DFT) in one or more dimensions, of arbitrary input size,
$PKGNAME: and of both real and complex data (as well as of even/odd data, i.e.
$PKGNAME: the discrete cosine/sine transforms or DCT/DST). We believe that
$PKGNAME: FFTW, which is free software, should become the FFT library of choice
$PKGNAME: for most applications.
$PKGNAME:
