Hey everybody. I have a homework which asks me to create GUI which will allow user to enter two numbers, then choose an operation (addition, substraction, multiplication, division) by using radio buttons, and then will give the result when they click the push button.
Here's what I've tried. I tried to contain all the codes in Pus Button Callback. It does not work: ("sonuc" is the result of the operation. It is the tag of my static text box.)
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
x = get(handles.sayi_1, 'String');
x = str2num(x);
y = get(handles.sayi_2, 'String');
y = str2num(y);
switch get(eventdata.uibuttongroup1, 'Tag')
case t
islem = x + y;
set(handles.sonuc, 'String', islem)
case c
islem = x - y;
set(handles.sonuc, 'String', islem)
case cc
islem = x * y;
set(handles.sonuc, 'String', islem)
case b
islem = x / y;
set(handles.sonuc, 'String', islem)
end

Try changing
switch get(eventdata.uibuttongroup1, 'Tag')
to
switch get(handles.uibuttongroup1.SelectedObject)
And you need to change t, c, cc and b to the correct handles of your radiobuttons (probably handles.radiobutton1, handles.radiobutton2 ....)

My bad, it needs to be
switch get(handles.uibuttongroup1,'SelectedObject')
