- Check state-space matrices and ensure they are 2-D. - 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, Darray_like, optional
- State-space matrices. All of them are None (missing) by default. See - ss2tffor format.
 
- Returns:
- A, B, C, Darray
- Properly shaped state-space matrices. 
 
- Raises:
- ValueError
- If not enough information on the system was provided.
