WebExample #1. def ifft2(data): """ Apply centered 2-dimensional Inverse Fast Fourier Transform. Args: data (torch.Tensor): Complex valued input data containing at least 3 dimensions: dimensions -3 & -2 are spatial dimensions and dimension -1 has size 2. All other dimensions are assumed to be batch dimensions. WebFFT (Fast Fourier Transform) refers to a way the discrete Fourier Transform (DFT) can be calculated efficiently, by using symmetries in the calculated terms. The symmetry is highest when n is a power of 2, and the transform is therefore most efficient for these sizes.
