Hi,
GIF use a lossless compression. Therefore, you cannot change the "quality" of gifs. However, you can change the size of the frame of the gif with the steps below:
  1. Import the gif file into the workspace.
  2. Grab the axes object of the gif.
  3. Set axes position something like below
>> axes('Units', 'pixels', 'Position', [10, 10, 100, 200]);
The above code sets position units to ‘pixels’ & position as ‘[10, 10, 100, 200]’.
For more information on ‘axes’ function, refer to this link.

Thanks Dr Mishra, thank you very much for the comments, but I guess change the size won't solve the resolution problem right?
