Re: [Matlab-emacs-discuss] issue with setting up matlab-mode on mac OS with MATLAB 2019b

[Roman G. <rom...@gm...>]

Hi Eric,

I had the same issue as Shervin using matlab-mode installed via MELPA
with emacs 26.3 on OS X 10.15.1. The MELPA version number for
matlab-mode is 20191223.2012. The issue was that the toolbox/+emacs
directory was for some reason not installed by emacs; after checking
out the repo and manually copying it in, everything seems to be
working fine.

Cheers,
Roman

$ emacs --version
GNU Emacs 26.3

$ uname -s -r
