             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);

在 MATLAB Online 中打开

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');
