Comment on Add FFT in Metal Performance Shaders
Hi, I'm working with 128x128x512 tensors, so in order to execute the fourier transform all over the tensor I'm looping 512 times over the FFT2 function using LOGN0 and LOGN1 = 7, because my vectors length are 128. I am still experimenting ways to get the fastest FFT2 over tensors with vDSP so if you have any tips on how I can speed it up I would really appreciate. Thank you !
