Creating and Manipulating Models

Deleting Parts of an LTI Array

You can use indexing to delete any part of an LTI array by reassigning it to be empty ([]). For instance,

• sys = rss(4,3,2,5,2);
  sys(1,:) = [];
  size(sys)
  5x2 array of continuous-time state-space models
  Each model has 2 outputs, 2 inputs, and 4 states.
  

deletes the first output channel from every model of this LTI array.

Similarly,

• sys(:,:,[3 4],:) = []
  

deletes the third and fourth rows of this two-dimensional array of models.
