Hello, I am looking for a way to programatically retrieve the portnames of a stateflow chart.
Curiously get_param(gcb,'OutputSignalNames') returns a cell array of strings with the names of all outports of the chart. However get_param(gcb,'InputSignalNames') returns an empty cell. I tried several other parameters, aswell as analyzing the PortHandles of the chart directly, but without success.
Why does 'InputSignalNames' return a blank cell? Are there certain prerequisites for this parameter to work as expected? Are there alternative parameters?
Is there a possible workaround? E.g. is there an API for the model explorer which would allow me to parse the chart data for variables with "Scope" -> "Input"?
Thank you in advance!

Ran in:
I'm not sure what the InputSignalNames parameter is used for and there is little information about it in the Simulink documentation. It was also empty for me.
Alternatively, you can use the Stateflow API to get the information you are looking for. For example:
openExample('stateflow/ModelingASecuritySystemExample');
chartName = 'Security System';
chart = find(sfroot, '-isa', 'Stateflow.Chart', 'Name', chartName);
inport = find(chart, '-isa', 'Stateflow.Data', 'Scope', 'Input');
inport_name = arrayfun(@(x) x.Name, inport, 'UniformOutput', false)
inport_name = 7×1 cell array
{'D_mode' } {'W_mode' } {'M_mode' } {'Door_sens' } {'Win_sens' } {'Mot_sens' } {'Alarm_active'}

The documentation for that parameter is really not great. In my tests OutputSignalNames returned exactly what i was looking for, so i assumed that the InputSignalNames Parameter would work the same.
I tried your alternative solution and it works perfectly for Inports and Outports. Thank you very much!

Hi. I believe this works as Federico mentioned when the names are written on the connections. How would one find the names if the names are not written on the connection lines.?
I tried with the 'stateflow/ModelingASecuritySystemExample' for outports and it gives an empty array.

'InputSignalNames' contains informations of names on lines connecting inports

Yes. You are absolutely correct. Is there any workaround how to get the signal names if the names are not written on the lines connecting the ports.? Appreciate your help
