FFT Functions
The fast Fourier transform function library of Intel® oneAPI Math Kernel Library (oneMKL) provides one-dimensional, two-dimensional, and multi-dimensional transforms (of up to seven dimensions) and offers both Fortran and C interfaces for all transform functions.
Table "FFT Functions in Intel® oneAPI Math Kernel Library (oneMKL)"lists FFT functions implemented in Intel® oneAPI Math Kernel Library (oneMKL):
