Compute the discrete Fourier transform at specified frequencies, not using fft.Why one may need this?(1) MATLAB fft function computes the amplitude of signals only (no phase).(2) Once having the recorded time-series data, one often uses fft to do the spectral analysis. However, the frequency set...

Run this program with a small image of about 100x100 pixels its because though it works on image of any size but for large images the execution time is very high. So if you do not want to wait for a very long time use a small image.
