WebMar 22, 2016 · In this code n=5 is the order of your matrix, then diag (6*ones (n,1),0) will create a vector (length n) with all 6 and such vector will be placed in the 0-th diagonal. Such matrix will have zero elsewhere. Similarly diag (-4*ones (n-1,1),1) will create a vector (length n-1) with all -4 and such vector will be placed in the 1st superdiagonal.

WebAug 12, 2024 · Add a comment. 2. 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.
