MATLAB: Image Segmentation and Saving image

save as

hello I'm a final year student using Matlab for image segmentation but I have a problem. How do I save multiple pictures automatically? Please help, thank you
image_folder = 'C:\Users\ADMIN\Matlab\Implementasi';
outfolder = 'C:\Users\ADMIN\Matlab\Implementasi\output';
if ~isdir(outfolder); mkdir(outfolder); end
load mri %I presume it has the variable map in it
files = dir(fullfile(image_folder, '*.jpg'));
% filenames = fullfile({fileinfo.folder}, {fileinfo.name});
% total_images = numel(filenames);
for iFiles = 1:numel(files)
thisfilename = fullfile(files(iFiles).folder,files(iFiles).name);
% for n = 1 : total_images
% thisfile = filenames{n};
[~, basename, ext] = fileparts(image_folder);
citra = imread(thisfilename);
V = squeeze(citra);
fprintf('processing %s\n', basename);
citra3 = montage(reshape(V,size(citra)), map, 'Indices', 3);
outfile = fullfile(outfolder, sprintf(['%s-coba-%03d.%s',basename,ext]));
saveas(citra3, outfile);
end
