hi all i m doing cross correlation using xcorr() of two column vector which are datas generated by resuls of ansys. these datas for 3 microsec with 0.01 microsec time interval.these are equal in length and gives a plot having max value of cc is 145. this is a value of cross correlation constant. i need to know the value in terms of time. can i get the value in terms of time if yes than how?????? or i can say how i get the time lag between these two signals in microsec?????? my coading is x=input(:,2); y=output(:,2); t=input(:,1); n1=length(x); [cc lag]=xcorr(x,y); plot(lag,cc) find(cc==max(cc)); [
