So I am new to matlab and having trouble using the imwrite() function. I uncollaged an image (137 seperate images) and want to save the individual images to a new folder. How do I use the imwrite() function to save all the cropped images? I was using this post ... https://www.mathworks.com/matlabcentral/answers/73719-uncollage-a-collage-image

Code...

message = sprintf('Would you like to crop out and save each individual images?');
reply = questdlg(message, 'Extract Individual Images?', 'Yes', 'No', 'Yes');
% Note: reply will = '' for Upper right X, 'Yes' for Yes, and 'No' for No.
if strcmpi(reply, 'Yes')
	figure;	% Create a new figure window.
	% Maximize the figure window.
	set(gcf, 'Units','Normalized','OuterPosition',[0 0 1 1]);
	for k = 1 : numberOfBlobs           % Loop through all blobs.
		% Find the bounding box of each blob.
		thisBlobsBoundingBox = blobMeasurements(k).BoundingBox;  % Get list of pixels in current blob.
		% Extract out this zoop into it's own image.
		subImage = imcrop(originalImage, thisBlobsBoundingBox); 
        % Saving the cropped image
       **imwrite(subImage,'path to folder') ?? **
        
    end
end

folder = 'c:/wherever';
thisBaseFileName = sprintf('Image %3.3d', k);
thisFullFileName = fullfile(folder, thisBaseFileName);
imwrite(subImage, thisFullFileName);
