4 % DESCRIPTION: findParameters returns parameter names matching the given
5 % pattern.
6 %
7 % CALL:
8 % names = findParameters(sys, options)
9 %
10 % INPUTS:
11 % sys - ssm objects
12 % options - plist of options
13 %
14 % OUTPUTS:
15 % names - a cell-array of matches, one cell per input pattern.
16 % Each cell can contain a cell-array of matched parameter
17 % names.
