Re: [Matlab-emacs-discuss] emacsinit/ using emacs as an external Matlab editor

hi Eric, I tried using matlab-shell again.  Looks great.

A couple of questions: I wasn't able to get cedet to work as it gives the
following error message when I edit a Matlab file.  I tried both the cedet
in emacs 24.3 and downloading it from sourceforce, version 1.1.  I don't
know if this is a result of cedet not working, but when I get an error
message in Matlab-shell the line number pointing to the problem in the
Matlab code does not seem to appear as a clickable link.

I wasn't able to see how to report issues/ bugs in the Matlab-emacs
sourceforce page so am sending this here.

best, E
