%% Create Parametric Diagonal Matrix % Create a matrix with tunable diagonal elements and with off-diagonal % elements fixed to zero. %% % Create a parametric matrix whose initial value is the identity matrix. p = realp('P',eye(2)); %% % |p| is a 2-by-2 parametric matrix. Since the initial value is the % identity matrix, the off-diagonal initial values are zero. %% % Fix the values of the off-diagonal elements by setting the |Free| property % to |false|. p.Free(1,2) = false; p.Free(2,1) = false;
