trfmod

Description

To visualize the pole-zero structure of a SISO transfer function h .

job='p'

visualization of polynomials (default)

job='f'

visualization of natural frequencies and damping

Interactive simplification of h. trfmod opens a dialog window.

Examples

// with a transfer function
s=poly(0,'s');
gs=syslin('c',1/(s+1));
trfmod(gs)

// with a state-space matrix
A=diag([1,2,3]);
B=[1;1;1];
C=[2,2,2];
sys=syslin('c',A,B,C);
trfmod(sys)
