在 MATLAB Online 中打开

 [gifImage cmap] = imread('1232.gif', 'Frames', 'all');
  len=length(gifImage(1,1,1,:));
  for i=1:1:len
           image(app.UIAxes,gifImage(:,:,:,i));
           pause(0.1);
  end

Refer to my code above, i have tried it out, but it is something wrong that they change the background to yellow. Once i have time, i will try back here to see it.

在 MATLAB Online 中打开

info = imfinfo('parsley_classify.gif');
info(1).TransparentColor
   ans =
   217
info(1).ColorType
ans =
  'indexed'

So Kevin Chng's suggestion would have to be modified to something like

filename = 'parsley_classify.gif';
info = imfinfo(filename);
transparent_color = info(1).TransparentColor;
delays = [info.DelayTime] / 100;   %varies for each frame!
[gifImage cmap] = imread('parsley_classify.gif', 'Frames', 'all');
alphas = double(gifImage ~= transparent_color);
len = size(gifImage, 4);
for frame = 1 : len
   image(gifImage(:,:,:,frame));
   colormap(cmap);
   pause(delays(frame));
end

Note: MATLAB does not support automatic playing of GIF animations in traditional axes (I do not know about apps). However, it does support autoplay of GIF in Live Script; https://www.mathworks.com/matlabcentral/answers/422870-can-i-insert-an-animated-gif-into-a-live-script
