pydsm.delsig.partitionABCD

pydsm.delsig.partitionABCD(ABCD, m=None)

Partition ABCD ss description in A, B, C, D for an m-input sytem

Parameters

ABCDmatrix like 2D

input ABCD matrix providing the state space representation

mint or None, optional

number of inputs of state space system. If set to None, a guess is made from the ABCD matrix size (defaults to None).

Returns

(A, B, C, D)tuple of 2D ndarrays

the individual matrices composing ABCD

Notes

When the number of inputs is automatically guessed, the minimum acceptable value is take, considering the the system must have at least an input and an output.

If ABCD is an ndarray, then its content is not copied in A, B, C, D.
