An example C-file S-function for accessing simulink signals
* without using the standard block inputs. In this case, a floating
* bar-plot style scope is implemented. The signals that are selected
* on the diagram (via the mouse) are displayed by the scope. The
* companion file <matlabroot>\toolbox\simulink\blocks\barplotm.m
* receives the signal data and plots it. See the demo model,
* <matlabroot>\toolbox\simulink\simdemos\sfcndemo_barplot.mdl.
