For some reason emacs matlab-shell is returning an error when running autocompletion. The debugging output for a completion of "load Da[TAB]" is shown below. The closest thread that I've found in sourceforge was this and their solution did not work. I've also tried to reinstall matlab-mode without success. Thanks in advance for any help.
