I have two 5Sec signals and i want to do the cross corelation of both the signals.

a = xlsread(signals 5sec.xls);

t1 = a(:,1); %time (Time is same for both the signal)

yR1 = a(:,2); % 1st signal

yR2 = a(:,4); % 2nd signal

% Cross Correlation

[r,lags] = xcorr(yR1,yR2);

plot(lags,r,'color','r','linewidth',1.6);

But i want to do the delay of 1 sec and then do the cross correlation using the for loop, i must to iterate the signals 1sec to 5sec for 1st signal and same thing i have to repeate in negative direction also. so i can get the neagtive and positive both the pulses.

Please help me to grow my self.

Thank You
