在 MATLAB Online 中打开

for k=1:numel(fileNm)
  This = fileNm{k} ;
  if isempty(This) ; continue ; end   
  imshow(This) ;
  pause(3);
end

This assumes that you only want to display the image and that you do not mind if the window keeps changing size. If you want to process the image you would need an imread() step.

After imshow(), try title() with the filename

for k = 1 : numel(fileNm)
  thisFileName = fileNm{k};
  if ~isfile(thisFileName) ; continue ; end   
  imshow(thisFileName);
  caption = sprintf('File %d of %d : "%s"', k, numel(fileNm), thisFileName)
  title(caption, 'FontSize', 18);
  drawnow;
end
