Hi, I'm trying to do something very simple, but can't seem to get the if condition correct.
I want to find the average of (:,2:5) if the values in the first column of the matrix are below a certain average.
Thanks in advance,
Ready to be humbled---

If A is your matrix and tol stands for "a certain average,"
if mean(A(:,1))<tol
M = mean(A(:,2:5));
end

A = rand(5);
A1 = A(:,1);
A1(A1>.5) = mean(A(A1>.5,2:5),2)
Like this? If not, please provide a small example.
