I have to sum two matrix with different dimension, for example Px = [3x3] and Py = [6x6], how can I insert elements on the diagonal of Px between P11 and P22 for example to make it of the same dimension of Py?
% starting matrix Px = [1 2 3; 4 5 6; 7 8 9]; % Py = magic(6); % elements to increase Px: v = [a1 a2 a3]; % Final mat...
