            [baseFileName, folder] = uigetfile({'.tif';'.jpg';'.png';'.gif*'}, 'Select a file'); 
            fullFileName = fullfile(folder, baseFileName); 
            img1 = imread(fullFileName);
             i = rgb2gray(img1); 
            ff=vision.CascadeObjectDetector(); 
            bbox=step(ff,i); 
            dd=insertObjectAnnotation(img1,'Rectangle',bbox,'Face');
             pts=detectMinEigenFeatures(i,'ROI',bbox);
             imshow(dd,'Parent',app.UIAxes);

Help me please i should return this homework tomorrow

You have not indicated what error you get. If you put in disp() statements, how far do you get?

the error was when i convert my app to executable this code doesn't work

When you run the executable, does "Anchor's Aweigh!" start to play on your closest lineprinter ?

How do you know that it doesn't work?

If you convert the code to

            disp('Starting!')
            disp('line 1'); [baseFileName, folder] = uigetfile({'.tif';'.jpg';'.png';'.gif*'}, 'Select a file'); 
            disp('line 2'); fullFileName = fullfile(folder, baseFileName); 
            disp('line 3'); img1 = imread(fullFileName);
            disp('line 4');  i = rgb2gray(img1); 
            disp('line 5'); ff=vision.CascadeObjectDetector(); 
            disp('line 6'); bbox=step(ff,i); 
            disp('line 7'); dd=insertObjectAnnotation(img1,'Rectangle',bbox,'Face');
            disp('line 8');  pts=detectMinEigenFeatures(i,'ROI',bbox);
            disp('line 9');  imshow(dd,'Parent',app.UIAxes);
            disp('got to end');

then what shows up?
