MATLAB: Import Data from Simulink Model into Gui

Question

Hello, im trying to get Simulink data into my GUI. I have no problem to control my Simulink-Model via the set_param command. My Simulink model sends data from subsystem via outport/inport-block into a sink (display or scope).

The Data is a simple counter starting @ 1. Now i want to catch this data and connect it with my GUI to show it in statictext field.

I failed to use the get_param: get_param('Model/Out1','…') because there is no parameter which provides me with the counter information.

I googled a lot and found add_exec_event_listener.I integraded the listener to the simstart button, so if the listener registeres, the simulation is already running. but it doesnt work:

blk = 'test/In1';
event = 'PostOutputs';
listener = @updategui;
h = add_exec_event_listener(blk, event, listener);

after that i thouight i can simply update the edittext via:

    set(handles.text,'h')% code

You see i am stuck using this command. I also dont know if i can register a listener to a Inport or a Sink. Can you please help me? Thomas

There is a good example on the File Exchange that you can download to learn how to do it.

There is also a discussion here.
