To display confidence intervals for a specified number of standard deviations, use the following syntax:
h = iopzplot(model); showConfidence(h,sd)
where sd is the number of standard deviations of a Gaussian distribution. For example, a confidence value of 99% for the nominal model curve corresponds to 2.58 standard deviations.
Plots zeros and poles of the model on the S-plane or Z-plane for continuous-time or discrete-time model, respectively.
To plot the poles and zeros of the model sys, use the following command:
