Hi,

 Block comments should be supported for font lock.  The version in CVS
found from matlab-emacs.sf.net should have it.

 Because MATLAB comments and block-comments can not be identified w/
the classic Emacs mechanism, you may find some delays while
highlighting these multi-line structures, much as if 0, end structures
are highlighted.  C-l will often solve the problem.

Good Luck
Eric

[Matlab-emacs-discuss] a block comment in an m-file

[Sergey L. <sli...@gm...>]

It seems matlab-mode does not recognize a block comment in an m-file: %{ 
----------- %}
Is there any fix to make it works?
Thank you.

[Juan C. B. <bo...@cs...>]

(setq scroll-step 1)             ; is not satisfactory
(setq scroll-conservatively 100) ; does the trick
I don't think is a very elegant solution though
"scroll" does not appear in matlab.el so I presume I have to dig out this 
mole from the emacs manual.
Thanks for your advice.
Cheers,
JC!

That's related to scrolling.  If you just move the cursor past the
bottom line in a buffer, it would do something similar.

I think if you set 'scroll-step' to non-0, you can specify how much to
scroll by when this happens.

[Matlab-emacs-discuss] Annoying recenter (C-l) after each command execution

[J. C. <bo...@cs...>]

Hi all,
As the topic says, it looks like after every single command execution that 
ends up filling more than half the emacs buffer it runs in an emacs Ctrl-L is 
executed.
I will appreciate if someone provided me with some hints on how to get rid of 
that behaviour.
Thanks in advance.
JC!

Something Mathworks has in it's Editor. i.e.

%% Do something
% this is a "paragraph"
x=1:100
y = cos(x);

%% Plot something
% this is another "paragraph"

plot(x,y)
xlabel('x');
ylabel('y');

%%%%

I find it very useful to run parts of long scripts this way.  When  
analyzing data you can either make an m-file for each "block" of  
code, which gets unwieldly fast, or do it all in one long script.    
Usually the script takes too long to run everytime you want to change  
the xlabel on a plot so running bits of it is very convenient. You  
can highlight a block and run it, but that requires more keystrokes.   
Blocking the code like this is invaluable to my work flow.

Cheers,  Jody

Hi,

  Thanks.  I know this feature is something I have had some requests
for.  I like the idea of using paragraph-start, though I do not know
the origins of the current values. Another option might be to use
page-delimiter instead.  What is a paragraph of M code anyway? ;)

[Matlab-emacs-discuss] running a block of code

[Jody K. <jk...@uc...>]

Hi all,

In light of the new mailing list I thought I'd share this.  I kludged  
up the following snippet to mimic the Matlab editor's ability to run  
a block of code between two "%%" markers.   It also allows you to use  
"paragraph-forward" and "-backwards" on chunks of code.

Cheers,  Jody


(defun jmk-matlab-parastart ()
   "Set the paragraph start for matlab mode."
   (interactive)
   (make-local-variable 'paragraph-start)
   (setq paragraph-start "^\%\%" )
   (make-local-variable 'paragraph-separate)
   (setq paragraph-separate "^\%\%" ))

(add-hook 'matlab-mode-hook 'jmk-matlab-parastart)

;; Matlab function for evaluating the current "paragraph"
(defun jmk-matlab-run-para ()
   "Run the current paragraph."
   (interactive)
     (save-excursion
       (if mark-active (matlab-eei-eval-region (region-beginning)  
(region-end))
	(backward-paragraph)
	(setq beg (point))
