How to bring a output value from simulink model into matlab GUI

3 views (last 30 days)
I can feed a value from GUI to Simulink model(two inputs to a product block and a output(Display block form SIM lib)) and it works. But how to get the output value from SIM to GUI? To feed two inputs from GUI to Simulink model i have used the following code which is working fine
******* function edit1_Callback(hObject, eventdata, handles) ******* NewVal = str2double(get(hObject,'String')); ******* set_param('untitled1/Constant','Value',num2str(NewVal));*********
and to get the output from SIM to GUI i have used the following code which is not working
******* b = str2num(get_param('untitled1/Display','value'));********* set(handles.edit4,'string',b);*********
This simple thing is really frustrating. Help me out i don't want to die with this
