I'm been trying this kind of thing, since
org-export-html-mathjax-options doesnt
have anything to configure.

I don't think this looks very right though.


#+LATEX_HEADER: \usepackage{amsmath}

#+MATHJAX: align:"left" mathml:t path:"C:\Users\JohnT\Desktop\mj\MathJax.js"

#+BEGIN_HTML

<script type="text/javascript"

 src="C:\Users\JohnT\Desktop\mj\MathJax.js?config=TeX-AMS-MML_SVG-full,"C:\Users\JohnT\Desktop\mj\config\TeX-AMS-MML_SVG-full.js">
</script>

<script type="text/javascript"

MathJax.Ajax.loadComplete("C:\Users\JohnT\Desktop\mj\config\TeX-AMS-MML_SVG-full.js");

</script>

#+END_HTML


#+TEX

$$\begin{matrix}
  a & b & c \\
  d & e & f \\
  g & h & i
 \end{matrix}$$

#+END_TEX
