bordermatrix in MathJaX
It would be nice to have the option to use bordermatrix in MathJaX. Like below.

@DayuanJiang, I ended up just nesting a whole bunch of matrices:
$$\begin{matrix}
& \begin{matrix}A&C&G&T\end{matrix} \\\\
\begin{matrix}A\\\\C\\\\G\\\\T\end{matrix} &
\begin{pmatrix}1&2&3&4\\\\3&4&5&6\\\\3&4&5&6\\\\3&4&5&6\end{pmatrix}\\\\
\end{matrix}$$
which yields:
It's not perfect but hopefully close enough..
@DayuanJiang, you may already know this but the extra backslashes are a workaround for displaying MathJax in HTML (see http://docs.mathjax.org/en/latest/tex.html#tex-and-latex-in-html-documents).

I'm guessing you mean markdown (though some markdown processors have specialized TeX handling and do not require escaping).
For HTML, you'd primarily need to escape &, <, >.
Yes I'm using revealJS with Markdown. I was going to elaborate but then figured it was too much info :)
As a reference I have this macro:
bordermatrix: ['\\newcommand\\bordermatrix[3]{ \\begin{matrix} & \\begin{matrix}#1\\end{matrix} \\\\ \\begin{matrix}#2\\end{matrix} \\hspace{-1em} & #3 \\end{matrix}}', 3]
Usage \bordermatrix{top labels}{left labels}{content}:
\bordermatrix{A&C&G&T}{A\\C\\G\\T}{
\begin{pmatrix}1&2&3&4\\3&4&5&6\\3&4&5&6\\3&4&5&6\end{pmatrix}
}
This is the best for me:
\begin{matrix}
& \\
K_1 = \cfrac{EI_b}{L^3_b} \cdot
\left ( \vphantom{ \begin{matrix} 12 \\ 12 \\ 12 \\ 12 \end{matrix} } \right .
\end{matrix}
\hspace{-1.2em}
\begin{matrix}
y_1 & \theta_1 & y_2 & \theta_2 \\ \hline
12 & 6b & -12 & 6b \\
6b & 4b^2 & -6b & 2b^2 \\
-12 & -6b^2 & 12 & -6b \\
6b & 2b^2 & -6b & 4b^2
\end{matrix}
\hspace{-0.2em}
\begin{matrix}
& \\
\left . \vphantom{ \begin{matrix} 12 \\ 12 \\ 12 \\ 12 \end{matrix} } \right )
\begin{matrix}
y_1 \\ \theta_1 \\ y_2 \\ \theta_2
\end{matrix}
\end{matrix}
Result:
