%% Check System Controllability %% % Define |A| and |B| matices. A = [1 1; 4 -2]; B = [1 -1; 1 -1]; %% % Compute controllability matrix. Co = ctrb(A,B); %% % Determine the number of uncontrollable states. unco = length(A) - rank(Co) %% % The uncontrollable state indicates that |Co| does not have full rank 2. % Therefore the system is not controllable.
