Hey All,(adsbygoogle = window.adsbygoogle || []).push({});

does anyone know what algorithm matlab uses to determine the autocorrelation function when you use the 'xcorr' function. the matlab help page refers to a textbook:

"Orfanidis, S.J., Optimum Signal Processing. An Introduction. 2nd Edition, Prentice-Hall, Englewood Cliffs, NJ, 1996."

But I can't find a copy of this either online or at my library.

Cheers,

Thrillhouse
