How can I perform operations using matrix columns on different matrix columns?

For a school assignment I have been given a 326*27 table of values and I have to calculate the cross correlation for every combination of all the different columns in the table in order to continue with the assignment. This means that I need 1x2, 1x3,1x4...1x27; 2x3, 2x4, 2x5...2x27; 3x4, 3x5, 3x6...3x27 up until 27x27. Is there an existing algorithm that enables this kind of calculations and if not can anyone suggest a way to calculate it? Or at least give me a place to start looking? Thank you

edit* The corr() function wont work because when I call the function that calculates the cross correlation for the matrix I need to be able to set the max delay. And the corr() function doesnt allow the delay to be set

Try the corr function (in the stats toolbox).

I need to be able to set the delay on the cross correlation which isnt possible in the corr function as far as I can tell
