Notice that the middle column of the I/O group listing indicates whether the

In general, to specify M input groups (or output groups), you need an M-by-2
cell array org anized as foll ows .
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.
• Youcanchoosenottoassignanyofthegroupnameswhenyouassignthe
groups, and leave off the second column of this array. In that case,
- Empty strings are assigned to the group names by default.
- If you 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.
