FFTW (Fast Fourier Transform in the West)

Abstract
FFTW is a very fast C library for computing the Discrete Fourier Transform in one or more dimensions. The data can either be real or complex, of arbitrary input size, and not restricted to powersof-two. FFTW is free software (GNU public license). Published benchmarks on a variety of different platforms show that FFTW's performance is typically better than other FFT software available in public domain. Included in the distribution is also a parallel version of FFTW, which is based on MPI. The FFTW package was developed at MIT by Matteo Frigo and Steven G. Johnson.
