%% Compute Frequency-Limited Gramian % Compute the controllability Gramian of the following state-space model. % Focus the computation on the frequency interval with the most energy. %% sys = ss([-.1 -1;1 0],[1;0],[0 1],0); %% % The model contains a peak at 1 rad/s. Use |gramOptions| to specify an % interval around that frequency. opt = gramOptions('FreqIntervals',[0.8 1.2]); gc = gram(sys,'c',opt)
