MATLAB Compiler: sim() in app.Designer Standalone

Hello,

i own the Matlab Compiler aswell as the Simulink Compiler Toolbox for the Standalone application.

I tried to create a Standalone-exe from an app.Designer file which includes a call to a Simulink File :

simulation='Simulink-model.slx';

parameter={...};

for i = 1:length(parameter)

app.simin=app.simin.setVariable(parameter{i,1},parameter{i,2},"Workspace",app.simulation);

end

app.simin=Simulink.SimulationInput(app.simulation);

app.simout=sim(app.simin);

The execution with the app.Designer works and calls the Simulink Model as intendend.

Now i want to create a standalone-exe but the Matlab compiler is not recognising the Simulink-Model (i already added the Model to the required files) and outputs an error during compiling:

Could not find any Simulink model file in the static code analysis.

Would be great if smb has a solution for it

thx in advance

stay healthy

Hi @Florian Daberkow,

I understand that you are getting an error about the model not being found during static code analysis. I noticed a few issues in the code that you shared in your question. Try making these changes and see if this will help:

• On this line:

simulation = 'Simulink-model.slx';

model extension is redundant. Also, model name should be a valid variable name. Please change it to:

simulation = 'Simulink_model';

• This line should be moved before the loop:

app.simin = Simulink.SimulationInput(app.simulation);

• There is no need to explicitly add the model to required files. The way static analysis picks up a model is if the model is typed as a literal string when constructing a SimulationInput object. For example:

app.simin = Simulink.SimulationInput('Simulink_model');

Alternatively, you can place a %#function pragma somewhere in your app's code to let static code analysis know that you are using this model and it will add it for you:

%#function Simulink_model

Thanks,
