Yes this is true. This seems to be a restriction from 
matlab-shell-run-cell. I guess I'll just write a 
matlab-cell-shell-run-cell function that's more neatly integrated within 
the matlab-cell minor-mode.

The real restriction with matlab-cell is that I'm assuming that the cell 
header is "%%" followed by at least a space character - if there's no 
character right after the "%%", then this is not recognized as a cell 
header. This comes from the matlab-cell-cellbreak-regexp variable (which 
can be customized, of course).
I will change it to default to not requiring the space character after 
the "%%" since this makes more sense.

It still works fine, well with one exception at least for me, a cell
must end with an empty new line. For example

%%
t=0:0.1:1
x=sin(t)
%%

Does not work while

%%
t=0:0.1:1
x=sin(t)

%%

does

Well I thought of including in the docstring of matlab-cell-mode

But maybe this just me but I use `C-h m' quite a bit.

Not sure I can do real testing today, but hopefully tomorrow.

 1.   Done. I've added it to the lisp_LISP variable in the Makefile and
    can confirm that it builds fine.

 2. This is correct. I found no reason to rewrite matlab-shell-run-cell
    since it works fine as is. Let me know if you feel otherwise.

After a very very brief testing, some comments:

    1. Could you please include matlab-cell in the Makefile?

    2. So I understand your code does not generalise in any way
       matlab-shell-run-cell?

Could you maybe enhance the documentation of matlab-cell-mode, for
example describe the navigation functions.

The keyb binding is something we might discuss later

Thanks for the code

Re: [Matlab-emacs-discuss] Github Migration?

[Nidish N. B. <nid...@il...>]

Okay I've pushed the first version of the cell utils. This is the first 
time I'm making a substantial contribution to a package, so please 
forgive me if something I'm doing is not how you'd rather have it - 
happy to learn! :)

A few pointers:

  * All the new contributions are in a new branch called "matlab-cells":
    https://sourceforge.net/p/matlab-emacs/src/ci/matlab-cells/tree/
  * I've dumped all the code in matlab-cell.el and made it a minor-mode.
    All the new variables and functions are prefixed with "matlab-cell-"
  * The new minor-mode is enabled by default by calling its setup
    function in the define-derived-mode of matlab-mode in matlab.el
  * I see that matlab-cellbreak-face already exists so perhaps there's
    some duplication of efforts - it would make sense to remove 
    redundancies.
  * A large portion of the code is based on another package, python-cell
    : https://github.com/twmr/python-cell.el

The main features that the new minor-mode enables are:

  * It redefines the page-break character to "%%" so an overline is
    drawn over those, making it visually look better.
  * The current cell that point is in is highlighted by being boldfaced
    (this is customizable).
  * Convenience functions for moving point forward and backward by one
    cell (also support being called with prefix arguments).
  * Convenience functions for moving a cell up or down by a block
    (number-prefixes supported too).
  * Some more non-interactive convenience functions to help development.
  * I've not bound any of the functions to any keymap within the package
    yet.
    In my config though, these are the bindings I'm using (in case
    someone's interested):

                 ("C-v" . 'matlab-cell-forward-cell)
                 ("M-v" . 'matlab-cell-backward-cell)
                 ("C-<return>" . matlab-shell-run-cell)
                 ("C-c C-b" . (lambda () (interactive)
                                (save-window-excursion
                                  (matlab-shell-run-cell))
                                (matlab-cell-forward-cell)))
                 ("C-x n c" . 'matlab-cell-narrow-to-cell)
                 ("M-[" . 'backward-paragraph)
                 ("M-]" . 'forward-paragraph)
                 ("C-c <down>" . 'matlab-cell-move-cell-down)
                 ("C-c <up>" . 'matlab-cell-move-cell-up)

I'll appreciate comments and suggestions! :)

you merge that later into master)?
so that at least we can do some testing.

Eric and John let me decide, (great).

Since I am trying since for more than a year to get the package into
ELPA, did you sign the FSF papers (I might have asked you that in the
past, but, memory, you know)? If not are you willing to do so?

[Nidish N. B. <nid...@il...>]

All,

I've implemented some additional cell block behavior that makes using 
cells in matlab through emacs smoother. It's similar to the stock matlab 
GUI experience but better (IMO ;) ).

I was wondering where I should apply my patches since I remember a lot 
of discussion on migrating to github. What's the current status on this?
Shall I go ahead and make a merge request on Sourceforge itself?

Thanks!

Thanks, but I still do not understand why *fprintf* is not supported and
why the indenting should be important. 

When I have a bit more time, I will ask John explicitly 😇 since he

Hi Uwe,

My comments on the topic have grown to such a size that I decided it's 
better to make a post from them.

Please have a look here:

Hi

I decided to start a new thread, since I made some progress and it seems
there are at least two ways to execute matlab from an org buffer and
insert the result back into that buffer.

    1. Using the python engine matlab ships (I am not describing the
       setup now)
       Disadvantage 
       a. Not all matlab releases support all ptyhon versions. For
          example ptyhon 3.5 is only supported till 2019a

       b. It takes some time for the python engine to start

       Advantage

       a. The format of the result is very nice.

    2. Using the matlab-shell itself (thanks @Martin for pointing this
       out)
       Test Configuration:

       a. Start emacs -Q

       b. Load the following file

--8<---------------cut here---------------start------------->8---
(setq load-path (cons (expand-file-name "~/emacs/site-lisp/packages/src/Matlab/HG-Git/matlab-sf-hg")  load-path))
(load-file "/home/oub/emacs/init/custom-init-faces.el")
(require 'company-matlab-shell)
(require 'org)
(require 'gdb-mi)
(autoload 'matlab-mode "matlab" "Enter Matlab mode." t)
(setq auto-mode-alist (cons '("\\.m\\'" . matlab-mode) auto-mode-alist))
(autoload 'matlab-shell "matlab" "Interactive Matlab mode." t)
(org-babel-do-load-languages
 'org-babel-load-languages '(
                             (C . t) ; enable processing C, C++, and D source blocks
                             (matlab . t)
                             ;;(perl . t)
                             (octave . t)
                             (org . t)
                             (python . t)
                             (plantuml . t)
                             (shell . t)
                             ))

(setq org-babel-default-header-args:matlab
   '((:results . "output") (:session . "*MATLAB*")))

--8<---------------cut here---------------end--------------->8---

And load ob-octave-fix.el
 https://github.com/karthink/.emacs.d/blob/master/plugins/ob-octave-fix.el

Then the following code can be executed in a org buffer

#+begin_src matlab :results output latex :exports results  :eval never-export :wrap latex
clear all
  x = [1, 2, 3, 4, 5];
  disp(sprintf('|%d', x))
#+end_src

#+RESULTS:
#+begin_latex
x = [1, 2, 3, 4, 5];
disp(sprintf('|%d', x))
|1|2|3|4|5
#+end_latex


#+begin_src matlab :results output latex :exports results  :eval never-export :wrap latex
  clear all
  x = [1, 2, 3, 4, 5];
  disp(sprintf('|%d', x))
#+end_src

#+RESULTS:
#+begin_latex
|1|2|3|4|5
#+end_latex

That already indicates that the formatting needs care, moreover
=fprintf= is not supported
#+begin_src matlab :results output latex :exports results  :eval never-export :wrap latex
  clear all
  x = [1, 2, 3, 4, 5] ;
  fprintf('|%d', x)
#+end_src

#+RESULTS:
#+begin_latex
#+end_latex

So I need to investigate this a bit more.

In summary: the second solution works surprisingly well and is faster
than the python solution, but the formatting seems to me more restricted
as in the python case. 

Any comments?

Has  anybody tried  this out?

@John you talked about such  feature in the past.

Can you confirm this behavior?

Uwe

I couldn't disagree more.

Email has a feature called threading, that indicates you
graphically/visually which message is a reply to which.

Issues just present a linear order of messages. If I want to reply to say
the second message my answer is just appended at the end and therefore
does not provide any visual aid of navigation.

Moreover I read and write email in emacs, so I can use its power, insert
matlab code search etc etc, while there does not exist any emacs for the
issue system. Correct me please if I am wrong.

These are the two main reasons, that I much prefer email/mailing list
over the cumbersome, basic issue system.

No it is not. It is just very popular and I understand this is the main
reason why people want to have, at least a mirror, there.


And BTW I am also not a huge fan of merging via the web interface, I
prefer to do that on my private machine using the command line and emacs
if needed and not some web interface (but this is just me).


But as I said the correct repository should be chosen wisely (since
there already a bewildering amount of matlab mirrors/forks) and I still
have no write access to the matlab group of repositories.

[Vasco C. <vc...@gm...>]

I don't know how to contribute to this email discussions. So I'm not sure
if replying to this email is the correct way.

In response to latest "digest", regarding Github, I find that exchanging
views in Github "issues" is very straightforward and clean, while the
mailing lists are very cumbersome to process with too much copied content,
and hard to navigate.
I do not know if Gitlab is better than Github, but Github is way more
effective to exchange views on issues than the email exchange/digests.

Well, I am on tcsh, but this is not the point.

Yes I can, but mainly because during installation Matlab asks me to set
a symbolic link to /usr/local/bin

So that is why 
which matlab 

Return
/usr/local/bin/matlab

Of course, I am using the matlab-shell very often, but from a matlab
file (.m)

What I want to do is, to calculate 

    1. Matlab commands from an org buffer

    2. And insert the result in that buffer.

So it is in mine.

Again, I use the matlab-shell very often but from .m files.

I think I will start emacs -Q and load you configuration+minimal matlab conf
and see what happens.

I find in strange that in our case fprintf does not work.
It works for me in the matlab-shell and using my (complicated) python
engine solution

Well...

1. After installing matlab-support you should be able to Matlab from 
bash by typing the command

 >> matlab

Can you do that?

    a) if yes

        Can you evoke matlab-shell in Emacs? (M-x matlab-shell)

        Again, you should be able to do that after installing matlab-mode.

    b) if no:

        check what are the values of the variables: 
`matlab-shell-command` and `matlab-shell-command-switches`

        In my case they are equal: `matlab` and ("-nodesktop"), 
respectively, which is by default set in `matlab-shell.el` which is a 
part of matlab-mode package.

       Maybe you need to set them explicitely like here:

      https://swang251.github.io/2021/12/03/Matlab-in-Emacs/

      ???

Hi

Some comments, since it did not work as expected.

done.


Now I executed 

#+begin_src matlab 
x = [1, 2, 3, 4, 5];
fprintf('|%d', x)
#+end_src

And obtained in a different window:
--8<---------------cut here---------------start------------->8---

NameErrorTraceback (most recent call last)
<ipython-input-3-e039b5096438> in <module>
      1 x = [1, 2, 3, 4, 5];
----> 2 fprintf('|%d', x)

NameError: name 'fprintf' is not defined

--8<---------------cut here---------------end--------------->8---

So 

    1. the result is not inserted in my org buffer,

    2. Morever fprintf is not defined, let me suspect this is not matlab
       what is excecuted but octave. Am I right?

What do I miss here?

Your approach is indeed cumbersome.

In mine we need to:

1. Install `matlab-support` - a  debian package that enables matlab 
integration within the system:

sudo apt install matlab-support


2. In Emacs: install `matlab-mode` package

3. Download

https://github.com/karthink/.emacs.d/blob/master/plugins/ob-octave-fix.el

and put it somewhere  in Emacs search path.

4. My init.el content with matlab/org-babel configurations:

;; 
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; enabling org-babel
(org-babel-do-load-languages
  'org-babel-load-languages '(
                  (C . t) ; enable processing C, C++, and D source blocks
                  (matlab . t)
                  ;;(perl . t)
                  (octave . t)
                  (org . t)
                  (python . t)
                              (plantuml . t)
                  (shell . t)
                   ))

;; setup matlab in babel
(setq org-babel-default-header-args:matlab
   '((:results . "output") (:session . "*MATLAB*")))

;; octave/matlab-fix
;;;; (require 'ob-octave-fix nil t)    ; This is for older approach
(require 'ob-octave-fix)

;; 
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;


I do remember that this 'ob-octave-fix' is very important. Otherwise 
there are some problems...

This works with Emacs 29.1 and currently Matlab 2023b.

The code you provided returned nothing in my case and in order to obtain 
the same result I needed to tailor it a bit (Should there really be a 
call to 'fprintf'?):

#+begin_src matlab :results output latex :exports results  :eval 
never-export :wrap latex
   x = [1, 2, 3, 4, 5] ;
   disp(sprintf('|%d', x))
#+end_src

#+RESULTS:
#+begin_latex
|1|2|3|4|5
#+end_latex
