output. (See “Signal Types” on page 2-8 for definitions.) For example, the code specifies
that input 2 of model CSTR is an unmeasured disturbance. The last line causes the LTI
object to be displayed, generating the following lines in the MATLAB Command Window:
a =
C_A T
C_A -0.0285 -0.0014
T -0.0371 -0.1476
b =
T_c C_Ai
C_A -0.085 0.0238
T 0.0802 0.4462
c =
C_A T
T 0 1
C_A 1 0
d =
T_c C_Ai
T 0 0
C_A 0 0

Input and Output Names
The optional InputName and OutputName properties affect the model displays, as in
the above example. The toolbox also uses the InputName and OutputName properties to
label plots and tables. In that context, the underscore character causes the next character
to be displayed as a subscript.
