Re: [O] strange output when executing matlab using babel, strange ,

[John Kitchin]

I believe you are seeing org's escaping at play. It puts a comma in front of the leading *. It must think that it is a heading in org-syntax, and so it escapes it to avoid some issues.

I think here it is a bug since that is not a heading. can you use some other leading character? I don't think the * have any significance in latex.

Hi

I am running Ubuntu 16.06, matlab 2018b and  I am using the python
kernel to use matlab from within org mode


Thanks to John Kitchin, I have the following setting

* Lisp setting
#+BEGIN_SRC emacs-lisp
(setq org-confirm-babel-evaluate nil)   ;don't prompt me to confirm everytime I want to evaluate a block

;;; display/update images in the buffer after I evaluate
(add-hook 'org-babel-after-execute-hook 'org-display-inline-images 'append)


(add-to-list 'org-src-lang-modes '("matlab" . matlab))
(setq python-shell-interpreter "python3")

;; 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


* The problem

When I run

#+begin_src matlab :results output latex :exports results  :eval never-export
disp('*Step 3:*')
disp('*Step 3:*  Calculate this')
#+end_src


On obtain
#+RESULTS:
#+begin_export latex
,*Step 3:*
,*Step 3:*  Calculate this
#+end_export


Instead of

#+begin_export latex
*Step 3:*
*Step 3:*  Calculate this
#+end_export


Does anybody have an idea what is wrong there?
