Web1 day ago · 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 ... WebAug 25, 2010 · Hello, I’m hoping someone can point me in the right direction on what is happening. I have three code samples, one using fftw3, the other two using cufft. My fftw example uses the real2complex functions to perform the fft. My cufft equivalent does not work, but if I manually fill a complex array the complex2complex works. Here are some …
