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 = "zpk" --> S = zpk2ss(sys) S = S(1) (state-space system:) "lss" "A" "B" "C" "D" "X0" "dt" S(2)= A matrix = 0. 1. -0.3162278 0. -6. -3.1622777 0. 3.1622777 0.
