I'm using vim-commentary but having problems with matlab and octave scripts trying to comment like c blocks
in the vim-commentary documentation it says to do:
autocmd FileType matlab setlocal commentstring=%\%s
but it wasn't working for me. The solution was to open the matlab.vim file as admin
sudo gedit /usr/share/vim/vim74/ftplugin/matlab.vim
to the file
Now it works automatically when vim loads a matlab file!
