/* 
 * C++ S-function that changes the size of an output according to the
 * value of a parameter.
 *
 *   y = [ u  u  u ... u ]'
 *
 * To compile this C++ S-function, enter the following command in MATLAB:
 *
 *   >>make sfunSizeChange.cpp
 *
 * Then open the file "testSizeChange.mdl/slx" and start the simulation.
