Cross correlation of several rows within a matrix

Hola!

I have a matrix of 10 column, each column has measurements at different times. I have a second matrix also of 10 columns, each consisting of measurements at different times.

I want to carry out cross correlations of every combination within this matrix. Example, xcorr row 1 matrix 1 with row 1 of matrix 2, then row 1 of matrix 1 of row 2 of matrix 2 and so on. I would like correlations and time lag for each and every combination of columns.

I currently do this, but it means I have to do each row seperatly which is very time consuming.

[xc,lags] = xcorr(matrix1(:,1),matrix(:,2));

[~,I] = max(abs(xc));figure;

plot(lags,xc); legend(sprintf('Time delay %d',lags(I))); title('Column 1 matrix 1 xcorr with Column 2 matrix 2')

Gracias todos, Ben :)
