SystemsModelOrder
- The system sys can be a delay-free standard or descriptor StateSpaceModel.
- The order of a standard continuous-time systems model is the number of integrators in the model and for standard discrete-time systems, the number of integer delays in the model.
- For descriptor systems, the order is taken to be the dimension of the slow subsystem.
The order of a state-space model:
| Out[1]= |  |
The order of a descriptor state-space model:
| Out[1]= |  |
It can be computed as the exponent of the polynomial Det[s e-a]:
| Out[2]= |  |
