If you simply want the average of all the values without any consideration of matrix structure then simply

mean( A(:) )

works for any numeric variable A. If that isn't what you want you need to be more specific.

lina, what do the numbers represent??? For example is each row a point, and the first column are the x values and the second column are the y values? It's that kind of explicit explanation that you left out and Adam was (and still is) wondering about. I really think you need to read these guidelines.

OK, then we notice that the two arrays have different number of points, so you can't simply subtract them because they don't match up point for point. So, do you need to interpolate them so that you get a common set of x coordinates so that you can then subtract the y values to get differences?
