plzr

pole-zero plot

Syntax

plzr(sl)

Arguments

sl

A linear dynamical system, in state space, transfer function or zpk representations, in continuous or discrete time.

Description

plzr(sl) produces a pole-zero plot of the linear system sl.

Examples

s=poly(0,'s');
n=[1+s   2+3*s+4*s^2        5; 0        1-s             s];
d=[1+3*s   5-s^3           s+1;1+s     1+s+s^2      3*s-1];
h=syslin('c',n./d);
plzr(h);
