    Fast C routines to compute the Discrete Fourier Transform

long_description \
    FFTW is a C subroutine library for computing the \
    Discrete Fourier Transform (DFT) in one or more \
    dimensions, of both real and complex data, and of \
    arbitrary input size. We believe that FFTW, which is \
    free software, should become the FFT library of choice \
    for most applications. Our benchmarks, performed on a \
    variety of platforms, show that FFTW's performance is \
    typically superior to that of other publicly available \
    FFT software. Moreover, FFTW's performance is portable: \
    the program will perform well on most architectures \
    without modification. \
    This port is of fftw version 3.x. It has many \
    improvements relative to 2.x, but is not backwardly \
    compatible.
