zpk2ss
Zero pole gain to state space
Syntax
S = zpk2ss(sys)
Arguments
- sys
A linear dynamical system in zero-pole-gain representation (see zpk).
- S
The state space representation of sys.
Description
Converts a zero pole gain representation to state space.
Examples
--> sys = zpk([2;1], [0;-3-%i;-3+%i], 2.5, "c")
sys =
(s-2) (s-1)
2.5 -------------
s (s^2+6s+10)
--> typeof(sys)
ans =
