Detect change to function-call S-Function

Detect change in a signal and output a function call that can drive downstream dependant blocks

The "Detect Change" block works great for outputting a Simulink Signal, but oftentimes you may wish to output function-call to trigger some downstream logic of function-called subsystems. Here is an S-Function that does just that

(Ensure your compiler is set up properly)

mex sfun_detect2funcall.c
sim Model_detect2funcall
