There is a slightly more performant way of using diag to get indices to a diagonal: n = 5; % matrix size M = reshape (1:n*n,n,n); % matrix with linear indices indices = diag (M, ii); % indices to diagonal ii. However, it is much easier to just compute the right indices directly. broadway boston lottery
