The MKL_FFT function (Intel Math Kernel Library Fast Fourier Transform) returns a result equal to the complex, discrete Fourier transform of Array. The result of this function is a single- or double-precision complex array. MKL_FFT is faster than FFT, but does not support more than 7D FFT transforms. It is called by the FFT function in every case except when the DIMENSION keyword is not present or zero, and the input is more than 7D. If the DIMENSION keyword is present and not zero, MKL_FFT is used.
