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?

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.

I don't think anything is wrong: org quotes lines that look like
headlines in the babel output by prepending the comma.

But it shouldn't I want the output to be surrounded by * * because then
it is exported to latex as \textbf

you are putting it in :results output latex though, so it won't be changed
on export. The contents of that block will be used verbatim I think in the
latex export. Maybe you can change latex to raw instead. Then the org
syntax will get converted to \textbf.
Otherwise, I think you have to put the latex markup in the output.
I still think it is a bug though, *step3:* does not act like a headline,
and isn't valid headline syntax even at the beginning of a line. I don't
think it should be getting escaped here.

Right! Raw is the solution
#+begin_src matlab :results output raw :exports results :eval never-export
#+end_src
Does precisely what I want, thanks a lot

That is what I think, it is a bug, Nick does not agree.
