Are you trying to create an upper tiangular matrix? Read about triu: https://www.mathworks.com/help/matlab/ref/triu.html

That was useful, but I want to index it as shown in the picture. Any idea how?
Are you trying to create something like this
H_alpha = [1 2 3 4];
M = zeros(numel(H_alpha));
for i = 1:numel(H_alpha)
M = M + diag(H_alpha(i)*ones(numel(H_alpha)-i+1, 1), 1-i);
end
Yeeees! Many thanks
I am glad to be of help! :)
