Hi all,
Say I have an array that's really large, say, 1000 x 1000, and I want to look only at the 10th element of each row, and the 10th element of each column, which would produce a 100 x 100 array. How can I do this?
Cheers, Henry

This works:
A10 = A([1 10:10:end], [1 10:10:end]);
with ‘A’ being your (1000x1000) array.
