Hi 

I have a org file with has a lot source blocks of the form 

#+begin_src matlab  :results output raw :exports code  :eval never-export
close all
N = 3; % number of chebyshev nodes
n = 1; % polytropic index
iters = 1; % iterations
j=[0 1 2 3];
z=cos((pi*j)/3);
y=1-(0.5*(z+1)).^2;
a=n*(8);
a2=eye(3+1)*a;
disp('\begin{align*}')
disp('A_{1,k-1}&=')
disp('\begin{pmatrix}')
fprintf('%g &%g &%g &%g\\\\\n',a2')
disp('\end{pmatrix}=OK\\')
disp('\end{align*}')
#+end_src

#+RESULTS:
\begin{align*}
A_{1,k-1}&=
\begin{pmatrix}
8 &0 &0 &0\\
0 &8 &0 &0\\
0 &0 &8 &0\\
0 &0 &0 &8\\
\end{pmatrix}=OK\\
\end{align*}

Two questions. 

    1. Is there any equivalent to org-update-all-dblocks for the source blocks?

    2. I want to export the org file to latex, in the current setting
       the source blocks are also exported. I tried
       #+begin_src matlab  :results output raw   :eval never-export
       but it did not help. 

Thanks 

Uwe Brauer

I think you want org-babel-execute-buffer:


Documentation
Call org-babel-execute-src-block on every source block in

the current buffer.

     2. I want to export the org file to latex, in the current setting

Normally, =:results output= should be enough, but there might be some
peculiarities with matlab blocks that change this behavior.

That did not work: I tried
#+begin_src matlab  :results output 

But when I exported the org file to latex, the matlab code was also
exported. Strange 

Anybody has an idea?

The only solution I am aware is to have something like this 



(defun my-latex-filter-src-blocks (text backend info)
  "Remove source blocks from latex export."
  (when (org-export-derived-backend-p backend 'latex)
    "%% [removed source block]\n"))

(defun my-html-filter-src-blocks (text backend info)
  "Remove source blocks from latex export."
  (when (org-export-derived-backend-p backend 'html)
    "%% [removed source block]\n"))

(add-to-list 'org-export-filter-src-block-functions
         'my-latex-filter-src-blocks)

(add-to-list 'org-export-filter-src-block-functions
         'my-html-filter-src-blocks)

If you want the output only, you also need to add ":exports results".

Do you use :exports results?

:results output switches to show what is printed to stdout

Hm not really

#+begin_src matlab :exports results
close all
N = 3; % number of chebyshev nodes
n = 1; % polytropic index
iters = 1; % iterations
j=[0 1 2 3];
z=cos((pi*j)/3);
y=1-(0.5*(z+1)).^2;
a=n*(8);
a2=eye(3+1)*a;
disp('\begin{align*}')
disp('A_{1,k-1}&=')
disp('\begin{pmatrix}')
fprintf('%g &%g &%g &%g\\\\\n',a2')
disp('\end{pmatrix}=OK\\')
disp('\end{align*}')
#+end_src
when I export this to latex I obtain 

\begin{verbatim}
\begin{align*}
A_{1,k-1}&=
\begin{pmatrix}
8 &0 &0 &0\\
0 &8 &0 &0\\
0 &0 &8 &0\\
0 &0 &0 &8\\
\end{pmatrix}=OK\\
\end{align*}
\end{verbatim}

Which is not what I want. I don't want a verbatim environment

See my answer to Eric

It does not do want I want
#+begin_src matlab :exports results
close all
N = 3; % number of chebyshev nodes
n = 1; % polytropic index
iters = 1; % iterations
j=[0 1 2 3];
z=cos((pi*j)/3);
y=1-(0.5*(z+1)).^2;
a=n*(8);
a2=eye(3+1)*a;
disp('\begin{align*}')
disp('A_{1,k-1}&=')
disp('\begin{pmatrix}')
fprintf('%g &%g &%g &%g\\\\\n',a2')
disp('\end{pmatrix}=OK\\')
disp('\end{align*}')
#+end_src

Leads to 

\begin{verbatim}
\begin{align*}
A_{1,k-1}&=
\begin{pmatrix}
8 &0 &0 &0\\
0 &8 &0 &0\\
0 &0 &8 &0\\
0 &0 &0 &8\\
\end{pmatrix}=OK\\
\end{align*}
\end{verbatim}

So at the moment the only solution I can think of is to use the code I
posted 

(defun my-latex-filter-src-blocks (text backend info)
  "Remove source blocks from latex export."
  (when (org-export-derived-backend-p backend 'latex)
    "%% [removed source block]\n"))

(add-to-list 'org-export-filter-src-block-functions
         'my-latex-filter-src-blocks)

Uwe,

In my testing (using octave since I don't have matlab, but I hope it's
similar), using = :exports none :results output raw= seems to produce the
desired output:

#+begin_src octave :exports results :results output raw
close all
N = 3; % number of chebyshev nodes
n = 1; % polytropic index
iters = 1; % iterations
j=[0 1 2 3];
z=cos((pi*j)/3);
y=1-(0.5*(z+1)).^2;
a=n*(8);
a2=eye(3+1)*a;
disp('\begin{align*}')
disp('A_{1,k-1}&=')
disp('\begin{pmatrix}')
fprintf('%g &%g &%g &%g\\\\\n',a2')
disp('\end{pmatrix}=OK\\')
disp('\end{align*}')
#+end_src

#+RESULTS:
\begin{align*}
A_{1,k-1}&=
\begin{pmatrix}
8 &0 &0 &0\\
0 &8 &0 &0\\
0 &0 &8 &0\\
0 &0 &0 &8\\
\end{pmatrix}=OK\\
\end{align*}

Which renders the matrix correctly. I first tried with =:exports results=,
but that for some reason results in the results being included twice in the
LaTeX output. I'm not sure why.

Hope this helps,
--Diego

That's it. That solves it, thanks so my function is not necessary. Good

The problem with =raw= is that you may find you have to manually delete
the previous results if you change and re-execute the src block.  Use
=latex= instead.
