zp2ss

Zero-pole to state-space conversion.

Syntax

[A, B, C, D] = zp2ss(Z, P, K)

Inputs

Z
Zero locations.
Dimension: vector | matrix
P
Pole locations.
Dimension: vector
K
System gain factor.
Dimension: double

Outputs

A
The state matrix (n x n), where n is the number of states.
B
The input matrix (n x p), where p is the number of inputs.
C
The output matrix (q x n), where q is the number of outputs.
D
The direct transmission matrix (q x p).
