Finding the percentage of similiarity of two signals in matlab
https://www.dsprelated.com/showthread/comp.dsp/41350-1.php
xcorr is the matlab cross correlation function. It measures similarity between two given signals, as a function of the relative time-shift between them. (The length of the result is 2N - 1 (minus, not plus).) As Rune said, it is not clear what it is you really want, so you should try to describe your problem better.
