Owning Class: linear systems

Requires: MathScript RT Module

Syntax

[e, f, g] = ss_to_zpk(a, b, c, d)

Legacy Name: ss2zp

Description

Converts a state-space to a zero-pole-gain representation of a transfer function. ss_to_zpk supports only SISO systems.

Examples

Inputs

Name Description
a, b, c, d Specify the system matrices of the state-space.

Outputs

Name Description
e Returns the zeros of the transfer function. e is a vector.
f Returns the poles of the transfer function. f is a vector.
g Returns the gain of the transfer function. g is a real number.
