Plot the poles and zeros of an LTI system in the complex plane. If no output arguments are given, the result is plotted on the screen. Otherwise, the poles and zeros are computed and returned.
Inputs
LTI model.
Line style and color, e.g. ’r’ for a solid red line or ’-.k’ for a dash-dotted
black line. See help plot
for details.
Outputs
Poles of sys.
Invariant zeros of sys.
The following code
s = tf('s'); g = (s-1)/(s-2)/(s-3); pzmap(g);
Produces the following figure

The following code
s = tf('s'); g = 1/(2*s^2+3*s+4); pzmap(g);
Produces the following figure
