So I think it is better to do: U = ifft2(ifftshift(O.*H)) in the last step of your code. According to the documentation, the sequences of calls ifftshift(fftshift(X)) and ifftshift(fftshift(X)) are not equivalent in case of odd sizes. 19-bpbd-kami-gunakan-warga-sekitar T14:26:28+07:00 monthly 0.5. I've just seen that Matlab advises to use ifftshift after fftshift insteaf of twice ifftshift (can't find the version in which it is introduced). So changing the final line to U = ifft2(fftshift(O.*H)) may solve the problem. So you have to come back to this format before doing the inverse FFT. 3 AnswersĪfter calling fft2, you call also fftshift to have the DC frequency at the middle.īut when you call ifft2, the function assumes that you have still the DC frequency at (1,1).
