%% View Confidence Region for Identified Model % Show the confidence bounds on the bode plot of an identified ARX model. % Copyright 2015 The MathWorks, Inc. %% % Obtain identified model and plot its bode response. load iddata1 z1 sys = arx(z1, [2 2 1]); h = bodeplot(sys); %% % |z1| is an |iddata| object that contains time domain system response % data. |sys| is an |idpoly| model containing the identified polynomial % model. |h| is the plot handle for the bode response plot of |sys|. %% % Show the confidence bounds for |sys|. showConfidence(h); %% % This plot depicts the confidence region for 1 standard deviation.
