I am running a simulink simulation+debugger programmatically. (This can be either from a GUI, or from matlab in batch mode)

Is there a way to configure the model or the sim+debug commands to not open and pop up the model?

DebuggerCommands = {'slist', 'quit'};
SimOptions = simset('Debug', 'on', 'debug', DebuggerCommands);
sim(<model name>, tfinal, SimOptions);
...

I verified that the model is already loaded when I get to the sim command, and only load_system is used within my scripts.

UPDATE: Just checked, it is the debugger that pops up the model. The sim() command alone will not open the model.

sim() does not pop up the model for me when I try -- but i have not turned on debugging when I have done so.

So I double checked and it seems to be the debugger that initiates the opening of the model. Both when I invoke it in the way shown above, as well as invoking sldebug(<model name>)

I'll rephrase my question above....

Hello Kai,

Yes, there is a way to configure the simulation commands to not open the model.

You can set the “OpenFcn” parameter of the model to an empty string using the “set_param” function. This will prevent the model from opening when you run the simulation.

Here's an example of how you can do this programmatically:

modelName = ''; % replace with the actual name of your Simulink model 
set_param(modelName, 'OpenFcn', ''); 
DebuggerCommands = {'slist', 'quit'}; 
SimOptions = simset('Debug', 'on', 'debug', DebuggerCommands); 
sim(modelName, tfinal, SimOptions);
