WebJun 14, 2024 · After all, the function in question is torch.fft, where “fft” stands for “fast Fourier transform,” which uses what you call the “divide-and-conquer” algorithm and runs in n log n. It would be false advertising if torch.fft instead used the sft* algorithm. *) “Slow Fourier transform” Best regards. K.
