Add this line to the first part of your for-loop

subplot(2,2,i)

And add this too

baseFileName = sprintf('%d.jpg',i);
fullFileName = fullfile(pwd, baseFileName);
if exist(fullFileName, 'file')
    c{i}=imread(fullFileName);
else
    c{i} = [];
    message = sprintf('Warning: %s does not exist', fullFileName);
    uiwait(warndlg(message));
end
