# [Tex/LaTex] How to get really big curly braces

I currently have the following equation that I would like to write:

\begin{equation*}
\pi(X)=\mathbf{N}_4\Bigg\{\left(\begin{matrix} 1
\\2\\1\\3\end{matrix}\right),\left(\begin{matrix}2 & 1 & 2 & 3 \\1 & 2 & 1 &
3\\ 2 & 1 & 3 & 3\\3 & 3 & 3 & 7\end{matrix}\right)\Bigg\}
\end{equation*}


But the curly brackets \Bigg\{ and \Bigg\} aren't big enough – is there a way to get bigger curly brackets?

Just use \left\{ and \right\} for the braces as well: \documentclass{article}

\usepackage{amsmath}

\begin{document}

Original equation:
\begin{equation*}
\pi(X) = \mathbf{N}_4 \Bigg\{ \left(
\begin{matrix}
1 \\ 2 \\ 1 \\ 3
\end{matrix}
\right), \left(
\begin{matrix}
2 & 1 & 2 & 3 \\
1 & 2 & 1 & 3 \\
2 & 1 & 3 & 3 \\
3 & 3 & 3 & 7
\end{matrix}
\right) \Bigg\}
\end{equation*}

Updated equation:
\begin{equation*}
\pi(X) = \mathbf{N}_4 \left\{ \left(
\begin{matrix}
1 \\ 2 \\ 1 \\ 3
\end{matrix}
\right), \left(
\begin{matrix}
2 & 1 & 2 & 3 \\
1 & 2 & 1 & 3 \\
2 & 1 & 3 & 3 \\
3 & 3 & 3 & 7
\end{matrix}
\right) \right\}
\end{equation*}

\end{document}
