iopzmap(sys) computes and plots the poles and zeros of each input/output pair of the LTI model sys. The poles are plotted as x's and the zeros are plotted as o's.

iopzmap(sys1,sys2,...) shows the poles and zeros of multiple LTI models sys1,sys2,... on a single plot. You can specify distinctive colors for each model, as in iopzmap(sys1,'r',sys2,'y',sys3,'g').

The functions sgrid or zgrid can be used to plot lines of constant damping ratio and natural frequency in the s or z plane.

For arrays sys of LTI models, iopzmap plots the poles and zeros o each model in the array on the same diagram.

Remarks

You can change the properties of your plot, for example the units. For information on the ways to change properties of your plots, see Ways to Customize Plots.

Example

Create a one-input, two-output system and plot pole-zero maps for I/O pairs.

H = [tf(-5 ,[1 -1]); tf([1 -5 6],[1 1 0])];
iopzmap(H)

iopzmap - Plot pole-zero map for I/O pairs of LTI model
