What is FFTW in Linux?
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).
Where do I put FFTW?
The required header files, fftw. h and rfftw. h , are located in the fftw and rfftw directories respectively; you may want to put them with the libraries, or wherever header files normally go on your system. FFTW includes test programs, fftw_test and rfftw_test , in the tests directory.
Is FFTW thread safe?
FFTW can be used in such an environment, but some care must be taken because the planner routines share data (e.g. wisdom and trigonometric tables) between calls and plans. The upshot is that the only thread-safe routine in FFTW is fftw_execute (and the new-array variants thereof).
