problem of displaying the progress bar on a separate figure

I created a GUI in which I insert a progress bar which starts when the output of my simulink subsystem goes to 1. The code is as follows:
I added the following lines to the OpeningFcn function:
% --- Executes just before MAJ is made visible.
function MAJ_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% varargin command line arguments to GUI_MAJ_Distance_OTA (see VARARGIN)
rectangle('Position',[0,0,(round(0))+1,20],'FaceColor','green', 'visible', 'off');
function Output_GUI(obj, event, handles)
rto1 = get_param('MAJ/X','RuntimeObject');
if((rto1.OutputPort(15).Data == 1) & (rto1.OutputPort(16).Data == 0))
set(handles.axes1, 'visible', 'on');
Max=1000; % Maximum value
for Index = 0 : Max
Once the output 16 is set to 1, the progression must reach 100%
I insert an axis on my HMI as shown here:
The problem is that the progress bar is displayed on a separate GUI and the progress is very slow.
I don't know what exactly the problem.
Why go to the trouble of making something yourself when Matlab has a nice and ready solution for you: waitbar. It has been in Matlab for a very long time, so even backward compatibility isn't an issue (in case you'dd need that).

You need to provide the handle to a waitbar to update the progress. Read the doc for more information about how to use it. I have next to no experience with Simulink, so I can't tell if there is anything you should be doing differently with that interface.
