How do i call a pushbutton of my GUI from a MATLAB function which is integrated into a SIMULINK model ?

Hi everybody !

I'm trying to control a driving Simulator from a GUI and some buttons placed on a steering wheel. The buttons have the function to turn the status of driving assistant Systems on or off. When i press a button on the GUI the callback function verifies the actual status of the driving assistant Systems based on a counter (global variable), loads a new Image(ON or OFF) into the button and raises the counter. My plan for the steering wheel button is the following: I get a signal (zero or one) in my SIMULINK model. This signal is the input of a MATLAB function which should call the GUI buttonfunction. So how do i call a pushbutton of my GUI from this function?

Note: This works fine in regular Matlab, I don't know anything about Simulink and whether there are reasons why you can't do this there.

Just factor out the function under your GUI into a different location that does not require the callback parameters, then you can call it from anywhere e.g.

function pbCallback( hObject, eventdata, handles )

calculateStuff( handles.someArg, handles.someOtherArgs )

Then calculateStuff is a function that takes relevant arguments and can be called from anywhere. You should never look to be calling a callback function explicitly from elsewhere in your code.
