It seems like you want to change Simulink's simulation mode programmatically and have these changes reflected in the Simulink UI.
Typically, programmatic control and UI-based control in Simulink are separate workflows and do not easily synchronize with each other. As a result, changes made using the "set_param" function may not immediately appear in the Simulink UI toolstrip.
One workaround is to close the model, load it into memory, make your changes via the command line, and then reopen the model. Here is an example of how you can do it:
close_system(mdl);
load_system(mdl);
set_param(mdl, 'SimulationMode', 'external'); % or 'normal'
open_system(mdl);
Here, “mdl” is the name of the Simulink model file that is currently under consideration. This sequence of functions ensures that changes are applied and reflected when you reopen the model in the UI.
For more information on these functions, you can refer to the following official documentation pages:
- open_system: https://www.mathworks.com/help/simulink/slref/open_system.html
- load_system: https://www.mathworks.com/help/simulink/slref/load_system.html
- close_system: https://www.mathworks.com/help/simulink/slref/close_system.html
I hope this helps!
