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.

There exist versions for single, double and long precision.

The library is available as 32-bit and 64-bit:

  • If you are compiling a 32-bit program, no special compiler options are needed.
  • If you are compiling a 64-bit program, you have to compile and link your application with "xlc_r" or "gcc -maix64" (or "xlC_r" and "xlf_r", respectively).


Current version: 3.3.7-1
