0 down vote favorite Is there a neat a fast way of computing the normalised cross correlation of two signals in MATLAB?
My two signals X and Y when I tried C = normxcorr2(X,Y) and plotted C my results did not look as I would expect

Look at the 'scaleopt' options. I think 'coeff' is the one you want.

Thank you very much in fact I have a follow on question - I am trying to determine the synchronicity between two oscillating signals. Which would be the better approach, to normalise the signals between 0 and 1 or to normalise the cross correlation? I dont really mind about the difference in amplitude but I would like to see synchronicity. Originally I thought to do cross correlation and look at the max of the graph however, I am not sure that this is the correct approach. I have also been looking at coherence of the spectra
