Plot Poles and Zeros at the Command Line
You can create a pole-zero plot for linear identified models using the iopzmap and iopzplot commands.
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.
| Command | Description | Example |
|---|---|---|
iopzmap,iopzplot | 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 iopzmap(sys) |
