Hello CG,
The function movcorr calculates the correlation coefficient for each point in the time series using a sliding window of specified length (in your case, 100 points). This means that each point in the output arrays r and p represents the correlation coefficient calculated over a window centred at that point, hence why you get a result for each of the 1534 points.
If you expected an output of one correlation coefficient every 100 points, you might consider modifying your approach. Here a suggestion:
After computing r and p, you can take every 100th value to get a reduced set of correlation coefficients.
downsampled_r = r(1:100:end);
downsampled_p = p(1:100:end);
I hope it helps with your query!
