S Mex function global variable values

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,

Can't you just clear the mex function from memory?

How could I do i? It looks like a normal block in simulink. How do i delete it from memory without changing a model?

[James Tursa]

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.

Thank you, clear mex did the job
