How to add Inputs/Outputs to Stateflow by code

I want to add an input to a Stateflow chart by code.

The way to do it without code is to go to tools/model explorer, click the add data button and choose the scope to be an input.

How do I do it by code?

The way I am currently doing is adding an IN port from matlab with the add_block function, but when I do it this way the port does not show in the model explorer. Is this a bug or is there another way to do it by code that adds the variable to the model explorer?

Problem solved. I did it by getting a handle to a state or chart. For example:

ch = sfgco; data = Stateflow.Data(ch); data.Scope = 'Input';
