Hi, I have a question concerning xcorr for the case of vector input.
The results of xcorr do not match with the ones suing the straight formula http://en.wikipedia.org/wiki/Autocorrelation#Estimation In particular taking the vector x = rand(4069,1); xcorr with option 'coeff' and 'biased' show a linear trend that the mentioned formula doesn't show. I guess this comes from the fact that the data has nonzero mean value and the formula removes it, while xcorr doesn't. Is this the expected behavior? If it is, we should improve the help text to mention this fact explicitly. Thanks -- M. Sc.
