在 MATLAB Online 中打开

baseFileName = sprintf('this_frame_%03d.jpg', k);

I don't think toolboxes are sold for older versions. If you want to add a new toolbox to your collection, then I think you'll need to upgrade to the current version. Anyway, even if they did, I don't believe that toolbox supported that version since I think it was released after March 2009, though I'm not sure.
