So for cross-correlation you need to select one of the elements outside the main diagonal (there are located self-correlation coefficients, in this case always equal 1). There is no difference if you would select ans(2,1) or ans(1,2) - there is no difference, if you compute the corr...
Compute the cross-correlation on the GPU. cc = xcorr2(offsetTemplate,template); Return the result to the MATLAB® workspace usinggather. Use the maximum absolute value of the cross-correlation to determine the shift, and compare the result with the known shift. ...
Copy Code Copy Command Compute and plot the estimated autocorrelation of a vector x. The largest spike occurs at zero lag, when x matches itself exactly. Get n = 0:15; x = 0.84.^n; [c,lags] = xcorr(x); stem(lags,c) Normalized Cross-Correlation Copy Code Copy Command Compute and...

Open in MATLAB Online I'm not sure I understand your confusion. You start out saying that you have two datasets that differ in magnitude but follow the same pattern, this suggest that if you cross correlate them, it would give you a high normalized cross correlation sequence value at the...
