How to use a variable from pop up menu callback to another callback functions like slider?

I made a popupmenu in GUI with tag Joint_PopUP like following. Whenever I select 'Head' or 'Head_End' from popupmenu, I make changes in 6 arrays of values. I want to use these 6 arrays of values inside another slider callback function in some calculation.

    function Joint_PopUp_Callback(hObject, eventdata, handles)
% hObject    handle to Joint_PopUp (see GCBO)
handles.Import_CSV;
str = get(hObject, 'String');
val = get(hObject,'Value');
  switch str{val};
      case'Head'          
              R_X=handles.Import_CSV(:,1); % I want to use this R_X array in slider callback for some calculation
              R_Y=handles.Import_CSV(:,2); % I want to use this R_Y array in slider callback for some calculation
              R_Z=handles.Import_CSV(:,3);
              T_X= handles.Import_CSV(:,4)/100;
              T_Y= handles.Import_CSV(:,5)/100;
              T_Z= handles.Import_CSV(:,6)/100;
%             handles.RX=R_X

      case'Head_End'

              R_X=handles.Import_CSV(:,7); % I want to use this R_X array in slider callback for some calculation
              R_Y=handles.Import_CSV(:,8); % I want to use this R_Y array in slider callback for some calculation
              R_Z=handles.Import_CSV(:,9);
              T_X= handles.Import_CSV(:,10)/100;
              T_Y= handles.Import_CSV(:,11)/100;
              T_Z= handles.Import_CSV(:,12)/100;

     end

how do I use those arrays inside another slider callback as shown below?

if true
    function StartPointSlider_Callback(hObject, eventdata, handles)
     % hObject    handle to StartPointSlider (see GCBO)
     handles.Import_CSV;
     [m,n] =size(handles.Import_CSV(:,1));
     set(handles.StartPointSlider,'Max',m);
     set(handles.StartPointSlider,'Min',0);
     val=get(hObject,'Value');
     set(handles.Start_Point_Show,'String',num2str(val));
     %R_X     %here i need the array from one of the case of popup menu that is already selected
     %R_Y     %here i need the array from one of the case of popup menu that is already selected
     % I do some calculations & plotting ....
    guidata(hObject, handles);
end

Thanks for your quick reply. But I have just done it using setappdata() and getappdata().
