在 MATLAB Online 中打开

Here's what i did:

downloaded and unzipped legappend (to a folder on the desktop)

used pathtool to create a new search directory to the folder

set the MATLAB workspace folder to the folder containing the demo

ran the demo

and i get these errors:

 Error using legend (line 120)
