I just can't believe displaying LaTeX math formula in
Octopress could be this easy.
 Add
gem 'kramdown'
to "GemFile", then run
bundle install
.
 Edit "_config.yml", replace
markdown: rdiscount
to
markdown: kramdown
, kramdown is a fast, pureRuby
Markdownsuperset converter.
 Open "source/_includes/custom/head.html", and add below scripts to
use MathJax, a decent js display
engine for mathematics.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
 <! MathJax > <script type="text/xmathjaxconfig"> MathJax.Hub.Config({ tex2jax: { inlineMath: [ ['$','$'], ["\\(","\\)"] ], processEscapes: true } }); </script>
<script type="text/xmathjaxconfig"> MathJax.Hub.Config({ tex2jax: { skipTags: ['script', 'noscript', 'style', 'textarea', 'pre', 'code'] } }); </script>
<script type="text/xmathjaxconfig"> MathJax.Hub.Queue(function() { var all = MathJax.Hub.getAllJax(), i; for(i=0; i < all.length; i += 1) { all[i].SourceElement().parentNode.className += ' hasjax'; } }); </script>
<script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeXAMSMML_HTMLorMML"> </script>

Now, let's enjoy the beauty of Gaussian
Distribution
\[
f(x;\mu,\sigma^2) =
\frac{1}{\sigma\sqrt{2\pi}}e^{\frac{1}{2}\left(\frac{x\mu}{\sigma}\right)^2}
\]
