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.
