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 ...

In MATLAB, crosscorrelation could be implemented by modifying and extending Example 2.13, and this has been done in the routine axcor which can be found on this book’s accompanying CD: [rxy,lags]=axcor(x,y); where x and y are the data to be crosscorrelated and rxy is the crosscorre...
