You can typeset matrices and other similar objects using an \texttt{array} environment. A couple of things to note:
|
||||||
|
|
||||||
|
\begin{itemize}[noitemsep]
|
||||||
|
\item \texttt{array} can only be used in a math environment.
|
||||||
|
\item You must declare the number and alignment of the columns by using \verb+\begin{array}{ccl}+. In this instance, we are declaring two centered columns and one left-aligned column.
|
||||||
|
\end{itemize}
