4 Position your mouse pointer in the textbox next to the design specification
characteristic.
5 Type a MATLAB relational expression in the textbox, using $ as a variable
name in the expression. Note that for arrays of MIMO models, you can
consider
$ to be an Ny-by-Nu matrix, if each model in the LTI array has Ny
outputs and Nu inputs. This allows you to specify different requirements on
different I/O channels.
6 Press Apply to implement your indexing selection.
For example, to display only the plot of the model with the maximum rise time
in the step response from the input to the first output, type
$(1,1) == max($(1,1))
in the textbox next to Rise Time.
Figure 6-18: Specifying Design Criteria to Select Models in the LTI Array
After selecting the Apply button, your LTI V iewer displays only the step
response of the model with the maximum rise time in the step response from
the input to the first output. The result of your action is displayed on the status
bar.
