Best Answer

You can use guidata
function popupmenu1_Callback(hObject, eventdata, handles)
b=get(handles.popupmenu1, 'value'); 
switch b 
  case 1 
    x=0:.1:1; 
  case 2 
    x=0:.1:10; 
  case 3 
    x=0:.1:100; 
end
handles.x=x
guidata(hObject,handles)
In the second callback
function popupmenu2_Callback(hObject, eventdata, handles)
x=handles.x
