i am writing code for face recognition system but it is giving me a few errors . Kindly help me to get rid of the errors . here is the code

faceDatabase = imageSet('FaceDatabaseATT','recursive');

figure;

montage(faceDatabase(1).ImageLocation);

title('Images of Single Face');

personToQuery=1;

galleryImage=read(faceDatabase(personToQuery),1);

figure;

for i=1:size(faceDatabase,2);

    figure;

    subplot(1,2,1);
    imshow(im1);
    subplot(1,2,2);
    imshow(im2);
end
    [training,test]=partition(faceDatabase,[0.8,0.2]);
    person=5;
    [hogFeature,visualization]=...extractHOGFeatures(read(training(person),1));
        figure;
    subplot(2,1,1);imshow(read(training(person,1)));
    title('Input Face');
    Subplot(2,1,2);
    plot(visualization);
    title('HOG Feature');
    trainingFeatures = zeros(size(training,2)*training(1).count,4680);
    featureCount=1;
    for i=1:size{training,2}
        for j=1:training(i).count
            trainingFeatures(featureCount,:)=extractHoG.Features (read(training(i)))

            trainingLabel{featureCount}=training(1).Description;
            featureCount=featureCount+1;
        end
        personIndex{i}=training(i)
        Description;
    end
    FaceClassifier=fitceoc(trainingFeatures,TrainingLabel);
    person = 1;
    queryImage=read(test(person),1);
    queryFeatures=extractHoGFeatures(queryFeatures);
    booleanIndex=strcmp(personLabel,personIndex);
    integerIndex=find(booleanIndex);
    subplot(121)=imshow(queryImage);
    title ('QueryFace');
    figure;
    figureNum=1;
    for person 1:5
        for j=1:test{person}.count
            queryImage=read(test(person),i);
            queryfeatures=extractHOGfeatures(queryImage);
            personLabel=predict(faceClassifier,queryFeatures);
            booleanIndex=strcmp(personLabel,personIndex);
            integerIndex=find(booleanIndex);
            subplot(2,2,figureNum);
            imshow(imresize(queryImage,3));
            title ('Query Face');

Can you be a bit more specific about the errors you are getting?
