Cross Backgrounds

This code calculates the cross-correlation for specified time windows over the duration of two input signals. The time windows can be shifted by increments smaller than the time window length. The code is based upon the 'xcorr' function.

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal).The package also includes two examples. One checks the calculation against the...
