Hi list,

Has any progress been made on this? I'm fairly new to org-mode and
org-babel but this sounds to me like a very useful feature.

This is also important for me (in fact, for octave). For now I used the template
file and I can tangle the code correctly, but since I didn't implement any
function for code execution tangling is all I've got.

I was also going to suggest that if someone did this, they might want to
try to address octave at the same time. 

Darlan -- would you like to share your initial version of octave
support? If we get it onto a git repository then we can all have a look
and maybe make a bit of progress. Either post it, or contact me off-line
for the admin details for http://repo.or.cz/w/org-mode/babel.git.

I don't use either language but here are some comments about the various
tasks and guesses about how hard they would be.

If someone could comment on the extent to which differences between
matlab and octave (running as command-line external processes) are going
to make shared org-babel support problematic that would probably be
useful.

- external process :results output
  Running octave as an external process under linux/OS X and collecting
  stdout shouldn't be too hard. Presumably same for matlab? Windows
  support: unavailable for matlab, but probably feasible for octave.

- external process :results value
  This basically involves (in matlab/octave) writing vectors and arrays
  to a tabular file (and then using existing code to import the org
  table, but this bit can be taken from the files for another language)

- :session
  At first glance it looks like there's an inferior octave mode that
  should be suitable for use
  with :session. Darlan -- do you have experience with this?

  http://www.gnu.org/software/octave/doc/interpreter/Running-Octave-From-Within-Emacs.html#Running-Octave-From-Within-Emacs

- Matlab :session on Windows
  Getting org-babel to work with the MatLab "EmacsLink" module may well be
  possible, but I would only be able to help very superficially.

Re: [babel] org-babel for matlab?

[Darlan Cavalcante Moreira]

[-- Attachment #1: Type: text/plain, Size: 312 bytes --]


I'm afraid I can't help much on this. I just used the org-babel-template.el file
provided by Eric and did a search and replace as told in the file comments in
order to make tangle work for octave and MATLAB. I didn't implement any function
(I only know enough lisp to understand my own .emacs file).

  In case it is useful to anyone I've hacked together something to
read back things from matlab's output using the diary mode, m-files,
and a bit of lisp combined with EmacsLink (which - sadly - is no
longer supported by the Mathworks on their most recent versions of
Matlab).  This was done on windows xp.


  This is still a few steps away from full orgmode integration, but it
is a bit nice.  Perhaps someone can build on it.

example use:

%in emacs matlab mode ss; a=1 fprintf(1,'%d\n',a) se;

% mark the above in emacs % ctrl-c ctrl-r % ctrl-c ctrl-i

%the result: %%%%%%%%%%%%% % 04-Mar-2010 20:49:45 a=1 a = 1
fprintf(1,'%d\n',a) 1 se;

%%%%%%%%%%%%%


%%%%%%%%%%%%%%%%%%%%%%%%


the .emacs changes:

    (defun my-matlab-mode-hook () (setq fill-column 76)
       (font-lock-mode 1) (auto-fill-mode 0) ; turn off auto-fill
       (imenu-add-to-menubar "Find")) ; where auto-fill should wrap
       (setq matlab-session-filename "session.txt") (defun
       insert-session-file () (interactive) ;;
       (matlab-shell-run-region (mark) (point)) (insert-file-contents
       matlab-session-filename)) (global-set-key "\C-c\C-i"
       'insert-session-file) (add-hook 'matlab-mode-hook
       'my-matlab-mode-hook)


ss.m %sessionstart

diary off; sessionfilename='C:\Documents and Settings\clong\My
Documents\MatlabToolboxes\stoph\session.txt'; eval(['delete '''
sessionfilename ''' ']); diary([sessionfilename]);
fprintf(1,'\n%%%%%%%%%%%%%%%%%%%%%%%%%%\n') fprintf(1,'%%
%s\n',datestr(now))


se.m %

fprintf(1,'\n%%%%%%%%%%%%%%%%%%%%%%%%%%\n') diary off;
