2 LTI Models
2-38
In general, to specify M input groups (or output groups), you need an M-by-2
cell array organized as follows.
Figure 2-2: Two Column Cell Array
When you specify the cell array for input (or output) groups, keep in mind:
•Each row of this cell array designates a different input (output) group.
•You can add input (or output) groups by appending rows to the cell array.
•You can choose not to assign any of the group names when you assign the
groups, and leave off the second column of this array. In that case,
- Empty strings are assigned to the group names by default.
- Ifyou append rows to a cell array with no group names assigned, you have
to assign empty strings (
'')tothegroupnames.
For example,
h.InputGroup = [h.InputGroup; {[3] 'disturbance'}];
adds another input group called disturbance to h.
You can use regular cell array syntax for accessing or modifying I/O group
components. For example, to delete the first output group,
temperature,type
h.OutputGroup(1,:) = []
ans =
[1x2 double] 'measurements'
