cupyx.scipy.signal.ss2tf(A, B, C, D, input=0)[source]#

State-space to transfer function.

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:

num (2-D ndarray) – Numerator(s) of the resulting transfer function(s). num has one row for each of the system’s outputs. Each row is a sequence representation of the numerator polynomial.
den (1-D ndarray) – Denominator of the resulting transfer function(s). den is a sequence representation of the denominator polynomial.
