Creating and Manipulating Models

Generating Random LTI Arrays Using rss

A convenient way to generate arrays of state-space models with the same number of states in each model is to use rss. The syntax is

• rss(N,P,M,sdim1,...,sdimk)
  

where

• N is the number of states of each model in the LTI array.
• P is the number of outputs of each model in the LTI array.
• M is the number of inputs of each model in the LTI array.
• sdim1,...,sdimk are the lengths of the array dimensions.

For example, to create a 4-by-2 array of random state-space models with three states, one output, and one input, type

• sys = rss(3,2,1,4,2);
  size(sys)
  4x2 array of continuous-time state-space models
  Each model has 2 outputs, 1 input, and 3 states.
