Is there a way to share a variable between simulink and matlab?

Hi guys, I have a question about simulink and matlab interference. I run a simulink model and m file simultaneously and I need to get the value of a variable from sim model to forward the progress of m file. I'm wondering if there's a way to let simulink and m file share a variable and make it accessible to the m file so that m file can reacts to the variable's changes.
Thank you

Sounds to me as if you should use a MATLAB Function Block with a Trigger Block

That would depend upon whether Simulink was started from the graphics menu or from sim() . If it was from sim() then it is not writing to the base workspace even with a To Workspace block. A MATLAB Function Block that is reading from the base workspace might not be much use. A MATLAB Function block that was passed the signal and used assignin('base') might be useful though.

You should use a To Workspace Block
When I investigated earlier this week I discovered that the data is written to the Base workspace if Simulink is started from the graphics menu, but if you call sim() within MATLAB then the data is written to the workspace of the function that calls sim(). (That function can then write it elsewhere.)

I think you can use a embedded matlab function available in simulink. In your application, input for the embedded matlab function could be the peak of the external sensor signlas and then you can write a script inside it to call one more function conditionally..

"embedded matlab function" is an older term. The newer is MATLAB Function Block
