Hello,
I have legacy C code with many global variables, which is bound into simulink be means of Mex-S-function.
When I stop and restart simulation I would expectd that new process is created and all those variables are to there init value (most of them 0, because not explicitely set and so on).
If I just start and stop and start it is unfortunately not the case.
If I start, stop, then rebuild S-function by "mex" command and then start it is the case.
Is there any way to say Simulink to unload the process on each simulation stop/end (I mean stop, not pause of course)?
Thanks,

Does the mex function itself show up in the list generated by the inmem( ) function? E.g.,
[M,X] = inmem;
Does it show up in the X list?

Use
clear all
everytime you run a simulation.
But this is not optimal as many others would suggest.
