`scipy.signal._lti_conversion:ss2zpk`

source: build-install/usr/lib/python3.14/site-packages/scipy/signal/_lti_conversion.py:357

Signature

def ss2zpk(A, B, C, D, input = 0)

Summary

State-space representation to zero-pole-gain representation.

Extended Summary

A, B, C, D defines a linear state-space system with p inputs, q outputs, and n state variables.

Parameters

A : array_like: State (or system) matrix of shape (n, n)
B : array_like: Input matrix of shape (n, p)
C : array_like: Output matrix of shape (q, n)
D : array_like: Feedthrough (or feedforward) matrix of shape (q, p)
input : int, optional: For multiple-input systems, the index of the input to use.

Returns

z, p : sequence: Zeros and poles.
k : float: System gain.
