gui

function pushbutton1_Callback(hObject, eventdata, handles) counter=1;
function pushbutton2_Callback(hObject, eventdata, handles)
counter=2;
function pushbutton3_Callback(hObject, eventdata, handles) counter=3;
function pushbutton4_Callback(hObject, eventdata, handles)
counter=4;
% — Executes on button press in pushbutton5. function pushbutton5_Callback(hObject, eventdata, handles)

end

Best Answer

Use guidata, which calls setappdata and getappdata internally:
function pushbutton1_Callback(hObject, eventdata, handles)
handles = guidata(hObject);
handles.counter = 1;
guidata(hObject, handles);
% And the same for the other callbacks...
function pushbutton5_Callback(hObject, eventdata, handles)
handles = guidata(hObject);
switch handles.counter
  case 1
  case 2
  case 3
  case 4
  otherwise  % No SWITCH without OTHERWISE
    error('Programming error')
  end
end
