  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;
