Is it possible to use the simulink model as a function in matlab?

I'd like to call a model I've created on simulink as a matlab function. Is this possible?

You can run a Simulink simulation in MATLAB using the sim command, do you mean this?

Hi Marina,

Yes, it is possible to call a Simulink model from within a MATLAB function. Here’s a step-by-step guide on how to do this:

• The "load_system" function loads the Simulink model into memory.

    % Load the Simulink model
    modelName = 'my_model';
    load_system(modelName);

• The "sim" function runs the simulation. The output of the simulation is captured in the simOut variable.

    % Run the simulation
    simOut = sim(modelName);

• Close the Model: The "close_system" function closes the model without saving any changes.

    % Close the model without saving changes
    close_system(modelName, 0);

Please refer the below documentations for load_system, sim and close_system:

sim: https://www.mathworks.com/help/simulink/slref/sim.html

close_system: https://www.mathworks.com/help/simulink/slref/close_system.html

I hope it helps!

With this approach, how do I pass input values into the simulation?
