+% getParameters returns parameter values for the given names.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% DESCRIPTION:  getParameters returns parameter values for the given
+%               names.
+%
+% CALL:
+%                vals = getParameters(sys, options)
+%
+% INPUTS:
+%                sys     -   ssm objects
+%                options -   plist of options:
+%
+% OUTPUTS:
+%                vals - an array of values, 1 value for each of the specified
+%                       names found in the model. For multiple input models, the
+%                       output values will be a cell-array of numeric vectors,
+%                       one cell per input system.
