## Latex

There are several matrix environments in Latex.

I will start with the "pmatrix" environment.

A very simple 2X2 matrix such as:

\[\begin{pmatrix}

a_{11} & a_{12} \\

\\

a_{21} & a_{22}

\end{pmatrix}\]

would be written as follows:

\[\begin{pmatrix}

a_{11} & a_{12} \\

\\

a_{21} & a_{22}

\end{pmatrix}\]
