Using the “find” function with “sfroot” does not directly limit its search to a specific Simulink model when multiple models are open because it operates at the level of the Stateflow API, providing access to all Stateflow objects in the MATLAB environment. To specifically find Stateflow charts within a particular model, a workaround can be employed to first identify the Stateflow machine associated with that model and then search within that machine.
Here is how you can implement this workaround:
modelName = "modelName";
load_system(modelName);
sfMachine = find(sfroot,"-isa","Stateflow.Machine",'-and','Name',modelName);
if ~isempty(sfMachine)
chartsInTargetModel = sfMachine.find('-isa', 'Stateflow.Chart');
disp(chartsInTargetModel);
else
disp('No Stateflow machine found for the specified model.');
end
Hope this helps!
