Appendix D: FFTW Interface to Intel® Math Kernel Library

Intel® oneAPI Math Kernel Library 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.
