You might dig around in ob-octave to see how it works. It should be able
to Matlab (and on Linux/Mac I believe it might). On Windows, it has been
broken for a long time due to the lack of a proper shell (maybe that can
be adapted in win10 though).
I vaguely recall making that matlab function to try it out on Windows
some years ago.
There is a Jupyter Matlab kernel now.
https://github.com/Calysto/matlab_kernel
I was able to use this (and installing the kernel, and making sure a
matlab is on the path):
#+BEGIN_SRC emacs-lisp
(add-to-list 'org-src-lang-modes '("matlab" . matlab))
;; set default headers for convenience
(setq org-babel-default-header-args:matlab
'((:results . "output replace")
(:session . "matlab")
(:kernel . "matlab")
(:exports . "code")
(:cache . "no")
(:noweb . "no")
(:hlines . "no")
(:tangle . "no")))
(defalias 'org-babel-execute:matlab 'org-babel-execute:ipython)
(defalias 'org-babel-prep-session:matlab 'org-babel-prep-session:ipython)
(defalias 'org-babel-matlab-initiate-session
'org-babel-ipython-initiate-session)
#+END_SRC
#+RESULTS:
: org-babel-matlab-initiate-session
To enable this:
#+BEGIN_SRC matlab :results output org drawer
x = [1, 2, 3, 4, 5];
fprintf('|%d', x)
#+END_SRC
#+RESULTS:
:RESULTS:
| 1 | 2 | 3 | 4 | 5 |
:END:
It is not much better output wise without the fprintf, but that seems to
be a feature of Matlab's output. I think Eric is probably right, you
will have use fprintf to get what you want.
I am not a big matlab user these days, so I do not have a sense for how
usable the kernel is. It does run in a session, which is a big
improvement over the other one I wrote.
