How fix speed of 3 For loops?

Hello

I have animated a proceess in GUI and used For loop to create animation of a mixing tank .However, the problem is my loop will work slow ecah ime more than before?

I am nott sure anyone know how to fix the problem?

Codes are provided below ,it is only to start button's function:

function start_Callback(hObject, eventdata, handles)
% hObject    handle to start (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA
%set(handles.stop_Callback, 'userdata', 0);
set(handles.stop,'userdata',0); 
set(handles.pause,'userdata',0);%defining the value of the pause-button 
set(handles.emergency_stop,'userdata',0);%defining the value of the emergency-stop-button
set(handles.reset,'userdata',0);

   if get(handles.reset,'userdata')% getting the response from Emergency-stop button
        title('Process is reset')   %creating title 
      return; %%stop process
    end
    
   axis([-10 10 -15 15]) 
     
for loop2=1:3 %it is a General Loop which loops all process
     title('stop button is applied')   %creating title
     if get(handles.stop,'userdata')% getting the response from stop button
        set(handles.stop,'userdata',1); %setting value of stop button
        break; %stopping loop
     end
    
  if get(handles.pause,'userdata')%getting the response from pause button
        uiwait(handles.figure1); %UIWAIT makes Guide wait for getting continue button's response 
        title(' process is paused') %creating title
  end
  
  
  if get(handles.emergency_stop,'userdata')% getting the response from Emergency-stop button
     title('process is stopped as Emergency') %creating title        
     break; %Stopping loop
