ifft matlab
Hello, I'm trying to apply the ifft function to the Fourier transform of a real signal S I know, so as to get S in the end. (basically ifft(ffft(S)) = S). My fft was made with ... ,But when i use inverse fourier transform ifft, i do not get real values, i get complex values and the result is not same as the original signal b. I am using y_source ...
