I am trying to detect faces in the image and label the images with predicted facial expressions, such as angry, disgust, happy, fear, surprise and neutral, the I want to crop these predicted facial expressions and save them into folders, as like, the face which is labeled angry should be cropped and saved in angry folder, the face which is labeled happy should be cropped and saved in the happy folder, and so on. I have done till face detection and facial expression prediction, I need help in the cropping and saving task.

Inside the for loop, but at the bottom of the for loop, do this:
% Get predicted class (facial expression) of this sub-image.
thisClass = label_str{i};
% Get output folder for this particular class.
folder = fullfile(location, thisClass);
if ~isfolder(folder)
% If folder does not exist, create it.
mkdir(folder);
end
% Save sub-image into this folder.
thisFileName = sprintf('%d.png', i); % Give it a number as the filename.
thisFileName = fullfile(folder, thisFileName); % Prepend the folder to get the full filename.
fprintf('Writing %s.\n', thisFileName);
% Do the actual write of the sub-image to the folder.
imwrite(classFace, thisFileName)

It's difficult for me to help you when I don't have the directory structure that you're using. Make it easy for me to help you by zipping up a folder of small images with the names that they have and explain where you'd like the sub-images to be saved. Have several, so you will probably have to resize the images to get the zip file to be smaller than the (I think) 5 MB attachment limit.

When reading your request, it would not be uncommon for people to be left with the impression that you are trying to avoid having to program the most difficult steps of your homework assignment.
