I want to have a matrix, where on the left side I have left brace with n written on it. But the current code I have does not produce the desired result. The left brace is not drawn due to some issue with SubMatrix
, and moreover, submatrices \mathbf{A}_1
and \mathbf{A}_2
are moved one column to the right. Any idea how to do this?
\documentclass{article}
\usepackage{amsmath,nicematrix}
\begin{document}
\[
\begin{bNiceArray}[last-col,margin]{w{c}{5em}|w{c}{3em}}
\\
\hspace*{-3cm} n & \mathbf{A}_1 & \mathbf{A}_2 \\
\\
\CodeAfter
\OverBrace[yshift=5pt]{1-1}{2-2}{\mathbf{A}}
\UnderBrace[yshift=5pt]{1-1}{3-1}{m_2}
\UnderBrace[yshift=5pt]{2-2}{3-2}{m_1}
\SubMatrix{\{}{1-1}{3-2}{.}[left-xshift=22pt]
\end{bNiceArray}
\]
\end{document}
