Discrete Fourier Transform (cupy.fft) — CuPy 12.0.0 documentation

WebЯ пытаюсь выполнить 2D-свертку, используя подход «FFT + point_wise_product + iFFT». При использовании матриц NxN метод работает хорошо, однако с неквадратными матрицами результаты неверны. Я прочитал всю документацию cuFFT в … WebNote that CuFFT semantics for inverse FFT only flip the sign of the transform, but it is not a true inverse. Similarly, the real to complex / complex to real variants also follow NumPy semantics and behavior. In the 1D case, this means that for an input of size N, it returns an output of size N//2+1 (it omits redundant entries, see the Numpy docs) diabetic main meals recipes
