.SH DESCRIPTION

The

.I libfftw

2.1.5 library 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).

Benchmarks, performed on on a variety of platforms, show that FFTW's

performance is typically superior to that of other publicly available

FFT software, and is even competitive with vendor-tuned codes. In

contrast to vendor-tuned codes, however, FFTW's performance is

portable: the same program will perform well on most architectures

without modification. Hence the name, "FFTW," which stands for the

somewhat whimsical title of "Fastest Fourier Transform in the West."

The full documentation can be seen by running

The FFTW package was developed at MIT by Matteo Frigo and Steven G.

Johnson.
