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