Hello all,
Let us say I have 3 column matrices (each is 2000x1) and I want to calculate the cross-correlation coefficients between them. Each matrix represents speed values at a certain elevation. Is the following way correct, where the correlation between the columns is stroed in the 'cr' matrix?
test = [a b c]; % where a, b, and c are the three column matrices put into one matrix
[cr,lgs] = xcorr(test,'coeff');

You should read the documentation, to determine whether a function does what you need. But I think you probably actually want
cr = corrcoef(test)
