LTI model order

Syntax

• ns = order(sys)
  

Description

ns = order(sys) returns the model order ns. The order of an LTI model is the number of poles (for transfer functions) or the number of states (for state-space models).

For LTI arrays, ns is an array of the same size listing the orders of each model in sys.

order(sys) is an overloaded method that accepts SS, TF, and ZPK models.
