plzr

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);
