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

delimiterssize;

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?

Best Answer

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}
