FFTW Interface to Intel® Math Kernel Library

Intel® oneAPI Math Kernel Library (oneMKL)
offers FFTW2 and FFTW3 interfaces to
Intel® oneAPI Math Kernel Library
Fast Fourier Transform and Trigonometric Transform functionality. The purpose of these interfaces is to enable applications using FFTW (www.fftw.org) to gain performance with
Intel® oneAPI Math Kernel Library
without changing the program source code.
Both FFTW2 and FFTW3 interfaces are provided in open source as FFTW wrappers to
Intel® oneAPI Math Kernel Library
. For ease of use, FFTW3 interface is also integrated in
Intel® oneAPI Math Kernel Library
.
