Figure 6-16: Step Response of the First Row of Models in m2d
There are a variety of ways you can index into the dimensions of an LTI array
using the textboxes located below each listbox. You can type both logical
expressions, or ones that define indices directly.
For example, suppose you have a variable
p defined in the MATLAB
workspace, representing a vector of parameters associated with the second
dimension of
m2d.
p = [1.1 5.3 10]
The variable p might, for example, represent t hree different operating
conditions for which you created the LTI array. To select indices specified by
these parameters in the second array dimension of
m2d, you can, for example,
type the following under the second listb ox.
p>5 % Choose the 2nd and 3rd indices in the 2nd array dim. of m2d
or
find(p<2) % Choose the 1st index in the 2nd array dim. of m2d
The plots of only
three models (as
opposed to the
six models in the
LTI array) are
shown here.
