WebMar 4, 2024 · As you said, a multidimensional fft consists in the successive execution of the Fourier transform along each dimension of the array. The problem here is that, after the first Fourier transform is applied to the real data, the result is now complex, and the following Fourier transforms don’t have hermitian symmetry.

WebIn Python, there are very mature FFT functions both in numpy and scipy. In this section, we will take a look of both packages and see how we can easily use them in our work.
