MATLAB: How to distinguish whether the model currently being viewed is a subsystem or stateflow chart

simulink

I would like to distinguish (true or false) with a command whether the current location is Stateflow Chart or Subsystem, when viewing the Stateflow chart at a specific location in the model in Simulink.

You can use a parameter on subsystem called SFBlockType as below.

isAChart = strcmp(get_param(gcb,'SFBlockType'),'Chart')

MATLAB: How to to locate all Stateflow 8.0 (R2012b) transitions with disconnected endpoints in a model

This can be done using the Stateflow API:

rt = sfroot;
modelHandle = rt.find('-isa','Simulink.BlockDiagram','$MODELNAME');
disconnectedTransitions = modelHandle.find('-isa','Stateflow.Transition','-and','Destination',[]);

The variable disconnectedTransitions will be an array of Stateflow.Transition objects that are not connected to a destination object. These transitions should come from any Stateflow chart within the model. $MODELNAME in the above code should be replaced with the name the model containing the charts/transitions. The VIEW method of the Stateflow.Transition object can be used to view the location of specific transitions.

MATLAB: How to add a Stateflow chart in an existing Simulink model using API

You can use the add_block function to add a Stateflow chart to an existing subsystem.

doc reference: http://www.mathworks.com/help/simulink/slref/add_block.html

So for example, to add a Stateflow chart to a subsystem called "Subsystem" in a model called "my_model", and name that chart, "MyChart", you would use the following command:

add_block('sflib/Chart','my_model/Subsystem/MyChart')
