Creating and Manipulating Models

Arithmetic Operations on LTI Models

You can apply almost all arithmetic operations to LTI models, including those shown below.

Operation	Description
+	Addition
-	Subtraction
*	Multiplication
/	Right matrix divide
\	Left matrix divide
inv	Matrix inversion
'	Pertransposition
.'	Transposition
^	Powers of an LTI model (as in s^2)

This following sections discuss these operations in detail:
