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.

Description

FFTW website  
Fastest Fourier Transform in the West, is a C library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data. Developed at MIT, it is by far the fastest implementation of FFT algorithm (upheld by regular benchmarks.)

Environment Modules

Run module spider FFTW to find out what environment modules are available for this application.

Citation

If you publish research that uses FFTW you may want to cite it as follows:
