Getting maxima source block to return and display latex equations

Question

I'd like my maxima source blocks to return either valid latex that I can display in the org-buffer, or an image of the results (a la imaxima). Ideally, the pure latex solution would be best.

Here is an example which I'd like to work.

#+BEGIN_SRC maxima :results output raw
C: matrix([1, -1], [1, 1]);
V: matrix([\sigma[11], \sigma[12]], [\sigma[12], \sigma[22]]);
tex(C . V . transpose(C));
#+END_SRC

#+RESULTS:
$$\pmatrix{\sigma_{22}-2\,\sigma_{12}+\sigma_{11}&\sigma_{11}-\sigma
 _{22}\cr \sigma_{11}-\sigma_{22}&\sigma_{22}+2\,\sigma_{12}+\sigma_{
 11}\cr }$$

The result doesn't render in my buffer.

Answer 1

Based on the babel's recommendation do you have this exports header someplace in the document?

#+header: :exports none

However for graphical rendering to file/displaying that file in-place, the manual recommends

#+header: :exports results
#+header: :results graphics

The other thing to check is the scale variable > 1 under org-format-latex-options. Yet I still get number-or-marker-p error every now and then.
