FFTW is a C subroutine library for computing the ...

fftw by Matteo Frigo 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 3.2a, which is free software, should become the FFT library of choice for most applications.
FFTW [fftw3.2a.exe]'s performance is typically superior to that of other publicly available FFT software, and is even competitive with vendor-tuned codes.
Features:
- Speed (Supports SSE/SSE2/3dNow!/Altivec, since version 3. 0. )
- Both one-dimensional and multi-dimensional transform.
- Arbitrary-size transforms. (Sizes with small prime factors are best, but FFTW - 0MB uses O(N log N) algorithms even for prime sizes. )
- Fast transforms of purely real input or output data.
- Transforms of real even/odd data: the discrete cosine transform (DCT) and the discrete sine transform (DST), types I-IV. (Version 3. 0 or later. )
- Efficient handling of multiple, strided transforms. (This lets you do things like transform multiple arrays at once, transform one dimension of a multi-dimensional array, or transform one field of a multi-component array. )
- Parallel transforms: parallelized code for platforms withCilk or for machines with some flavor of threads (e. g. POSIX). An MPI version for distributed-memory transforms is also available, currently only as part of FFTW 3.2a 2. 1. 5. machines with some flavor of threads (e. g. POSIX). An MPI version for distributed-memory transforms is also available, currently only as part of FFTW 2. 1. 5.
- Portable to any platform with a C compiler.
- Both C and Fortran interfaces.
