gives the order of the state-space model sys.


  • The system sys can be a standard or descriptor StateSpaceModel, an AffineStateSpaceModel, or a NonlinearStateSpaceModel, all with no delays.
  • 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 a descriptor StateSpaceModel, the order is taken to be the dimension of the slow subsystem.
