Is there a hidden workspace in Simulink other than the model workspace?

回答： Guilherme T Silva 2016-6-8

When running a Simulink model, I get unexpected behaviors if I don't call a clear all before the execution. Strange thing is that both the base and the model workspaces are empty. What could be happening? Where else can I look for those hidden variables?

Thanks!

I found out what was wrong: Simulink won't clear S-functions static memory from run to run. I'm using clear mex for that. Thanks!

One of things that clear all does is to clear out the parsed versions of routines (which you do not care about) along with their attached workspaces -- that is, any accumulated persistent variables, which could potentially be an issue.

Do you have any suggestion on how to debug this? How can I at least visualize that accumulated data?

There is no documented way to detect persistent variables in loaded functions and examine those variables -- other than doing a text search for "persistent" and putting in breakpoints.
