Cross correlation at 0 lag between two time series data sets

Hi everyone.

I am new at MATLAB. I want to do cross-correlation of two time series data sets at 0 lag and find the correlation coefficient for the same. Here I am attaching data sets as P and Q. the first column of data is time, while the second column is amplitude.

Isn't that just what the first example in the documentation for xcorr() does? Did you see it?

Also use corrcoeff() to get the correlation coefficient.

Hi! Yes, It is not working as I have not much more knowledge of it. Could you try please with given data.
