`scipy.signal._lti_conversion:zpk2ss`

source: /scipy/signal/_lti_conversion.py :306

Signature

def zpk2ss ( z , p , k )

Summary

Zero-pole-gain representation to state-space representation

Parameters

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

Returns

A, B, C, D : ndarray: State space representation of the system, in controller canonical form.

Notes

Array API Standard Support

zpk2ss has experimental support for Python Array API Standard compatible backends in addition to NumPy. Please consider testing these features by setting an environment variable SCIPY_ARRAY_API=1 and providing CuPy, PyTorch, JAX, or Dask arrays as array arguments. The following combinations of backend and device (or other capability) are supported.
