How to plot pole-zero in matlab?

To create pole-zero maps with default options or to extract pole-zero data, use pzmap . h = pzplot( sys ) plots the poles and transmission zeros of the dynamic system model sys and returns the plot handle h to the plot. x and o indicates poles and zeros respectively.

What does a pole-zero plot show?

A pole-zero plot shows the location in the complex plane of the poles and zeros of the transfer function of a dynamic system, such as a controller, compensator, sensor, equalizer, filter, or communications channel.

How do I stop zeros and poles in Matlab?

sysr = minreal(sys) eliminates uncontrollable or unobservable state in state-space models, or cancels pole-zero pairs in transfer functions or zero-pole-gain models.
