Thread Subject: stored variables

I have a simulink model that relies on inputs from the workspace. The problem is that once I run simulink, it seems to clear the variables; I have to re-run the m-files that load the variables before I can run simulink again. Is there a way to avoid this? It's annoying when trying to troubleshoot the model when each m-file takes several minutes to run. Thanks!

Check to see if you have any callback functions in your simulink model that clears those variables.

Sometimes a ToWorkspae block could also over-write your variable if the varialbe names are the same.
