Hi all,
Sometimes, there are reverse research questions in research studies. How can I turn all 5 to 1, 4 to 2, 3 remain the same, 2 to 4, and 1 to 5 in just column 3 of a 90 in 11 matrix? Is there any automatic command for it because it's widely used just like t-test.
Thanks

How about this?
A(:, 3) = 6 - A(:, 3);
