scipy.signal.abcd_normalize¶
- scipy.signal.abcd_normalize(A=None, B=None, C=None, D=None)[source]¶
Check state-space matrices and ensure they are two-dimensional.
If enough information on the system is provided, that is, enough properly-shaped arrays are passed to the function, the missing ones are built from this information, ensuring the correct number of rows and columns. Otherwise a ValueError is raised.
Parameters: A, B, C, D : array_like, optional
State-space matrices. All of them are None (missing) by default. See ss2tf for format.
Returns: A, B, C, D : array
Properly shaped state-space matrices.
Raises: ValueError
If not enough information on the system was provided.
