scipy.signal.ss2zpk(A, B, C, D, input=0)[source]¶ State-space representation to zero-pole-gain representation.
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.
