Hi
I have the following org file #+BEGIN_SRC matlab :tangle test.m :padline no :results none function [ll x]=mitest(A0,x0) % initialization format long epsi=1.e-3; nit=0; nmaxit=200; Delta=10; A=A0; while Delta>epsi & nit<nmaxit nit=nit+1; % counter #+END_SRC The basic idea is. That we do. We also will #+BEGIN_SRC matlab :tangle test.m :padline no y=A*x0; end #+END_SRC Now org-babel-tangle works nicely, but when I try to export the org file to latex via org-export-dispatch I obtain a latex file in which the source code is removed. What do I miss?? I am asked in the export process whether I want to evaluate the code, which I don't since it is a simple function not a code to be evaluated.
