How to draw pzmap in matlab?

Pzmap( sys 1, sys 2,..., sys N) creates the pole-zero plot of multiple models on a single figure. The models can have different numbers of inputs and outputs and can be a mix of continuous and discrete systems. For SISO systems, pzmap plots the system poles and zeros.

I found a bug of matlab. when I use the matlab function "pzmap" to draw the poles and zeros, these poles should be located on the unit circle,"" ·" : "Do not be bothered by that. You know that the magnitude of the pole should give you *^2+0

If the poles and zeros are associated with a discrete-time model, a unit circle is also drawn. For continuous-time models the real and imaginary axes are drawn.

This MATLAB function plots the zeros specified in column vector z and the poles specified in column vector p in the current figure window.

Yes, this will work, and pzmap works fine on discrete-time models. Your h here is not the same as the transfer function in your original post, though, which you"" ·" : "is it good approach. i have actual H(z) in z(-1) form h = tf([1 -1],[1 -3 2],0.1,'variable','z^-1')

This MATLAB function plots the poles and transmission zeros of the dynamic For more information about using and interpreting pole-zero maps, see pzmap ."Description · Examples · Input Arguments

Pzplot allows you to customize your figure. For example, the marker size or line width. An example of how to customize your figure: close all"Missing: draw | Must include: draw

This MATLAB function generates a grid of constant damping factors from 0 to sys = tf([2 -3.4 1.5],[1 -1.6 0.8],0.1); Ts = 0.1; figure() pzmap(sys) zgrid() axis equal.

Returns the system poles and (transmission) zeros in the column vectors p and z . No plot is drawn on the screen. You can use the functions sgrid or zgrid to plot
