problem of displaying the progress bar on a separate figure

Hi,

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) 
axes(handles.axes1); 
set(handles.axes1,'Xtick',[],'Ytick',[],'Xlim',[0 1000]); 
rectangle('Position',[0,0,(round(0))+1,20],'FaceColor','green', 'visible', 'off'); 
text(480,10,[num2str(0),'%']);

The code:

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 
    set(handles.axes1,'Xtick',[],'Ytick',[],'Xlim',[0 1000]); 
    for Index = 0 : Max 
        axes(handles.axes1); 
        cla(handles.axes1); 
        rectangle('Position',[0,0,(round(1000*Index/Max))+1,20],'FaceColor','green'); 
        text(480,10,[num2str(round(100*Index/Max)),'%']); 
  end
end

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).

I have the this code where Inputport is X and Outputport is Y

 function Output_GUI(obj, event, handles) 
rto1 = get_param('waitbar_test/Sub','RuntimeObject'); 
if((rto1.InputPort(1).Data == 1)  & (rto1.OutputPort(1).Data ~= 1)) 
       h = waitbar(0,'Please wait...'); 
steps = 10000; 
for step = 1:steps 
    % computations take place here 
    waitbar(step / steps) 
end 
close(h) 
end

When X = 1 the waitbar must start in parallel with the simulink counter. Once the timer finishes Y goes to 1 and the waitbar must reach 100%.

But that is not what happens. When X = 1 the waitbar starts and simulink is blocked so the counter does not progress anymore. The waitbar runs in a loop. and it is only when I close the waitbar that the counter starts counting.

I don't understand what the problem is.

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.
