How to change model properties of a .slx simulink model using the MATLAB script

Hello,

I am working on automated test scripts which involve calling mulltiple simulink models from inside a single simulink model. So I would like to access and edit the model porperties of all these simulink files at once using a matlab script.

For example, in the picture, I want to change the design Data definition from Base Workspace to Data Dictionary without having to open the simulink model and going to model properties, but directly from the command window. Does anyone know a way for it?

Model configuration settings can be controlled from MATLAB code using the get_param() and set_param() functions. Help will tell you the name of the parameter. In this case:

set_param(modelName,'DataDictionary',dictionaryName);

Hello Mark,

Thanks for your answer. However, in my case, specifically I need to change the model parameters to use "Base Workspace" instead of Data Dictionary. Is there a way for it?

I tried using BaseWorkspace in set_param, but it doesn't recognise that.

set_param(modelName,'DataDictionary','')

That works. Thanks!
