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.

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

Johnson. Please send email to fftw@theory.lcs.mit.edu so that we can keep
|
|
|
|
|
track of users and send you information about new releases. The latest
|
|
|
|
|
version of FFTW, benchmarks, links, and other information can be found at
