Re: [Matlab-emacs-discuss] Links and tab completion in matlab-shell

Hi Eric,
thanks a lot for the developing and updating of the matlab-emacs code.
It sometimes works fine for me -- in matlab-shell under emacs some error
messages are links, other are still not. Funnily, errors with more
dependencies seem to work. Simple errors in dump test files do not (like
one-line files [1+1+ ]).
One hint for other users who have problems with the emacs matlab shell.
I had to do some cleaning! First, updated to the new Matlab R2010a (was
using the test version sill) and eliminated old toolboxes. The problem
was that still an old opentoline.m was used. Now matlab uses the one
provided in matlab-emacs/toolbox (test: error messages in the native
matlab command window all link to and open emacs perfectly!!!). Second,
I had to clean matlab.el and matlab.elc from the emacs-goodies-el folder
--I guess these have been used instead of the updated matlab.el. Hope
this helps.
Thanks,
Evelina
