WebHá 2 dias · The way I see it, I would need to reshape my input image to a size of [8,4,8,4], and then permute the middle two indices for a final shape of [8,8,4*4], and then I could run the standard 2D batched FFT. I could do this with a custom CUDA kernel that would involve copy-pasting, but I was wondering if cuFFT already has this functionality (maybe ...
