Hi to all , I have a Matrix A = ones(5). How i can change the element value one by one to -1.
example A = [1,1,1]
A = [-1,1,1] A = [-1,-1,1] A = [-1,-1,-1]
But I want to do it for 5 X 5 matrix
Regards

Do you mean iteratively in a loop? E.g., changing elements one at a time in column order:
n = numel(A);
for k=1:n
A(k) = -1;
% Use A here
end
