如何为该矩阵添加标签标题？

我怎样才能为该矩阵添加这样的标题？

在此处输入图片描述

我试过这但由于开头是 A1/A2，因此无法使其适用于这种情况。

\documentclass[journal]{IEEEtran}
\usepackage{graphicx}
\usepackage{mathtools}
\usepackage{blkarray}
\usepackage{nicematrix}

\newcommand{\clr}[2]{\textcolor{red}{#1}/\textcolor{blue}{#2}} 

\begin{document}

\[
\clr {A_1}{A_2}=\begin{blockarray}{cccccccc}
 & V_1& V_2 & V_3 & V_4 & V_5 & V_6 & V_7   \\
\begin{block}{c(ccccccc)}
V_1 &  \clr{0}{0} &\clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} \\
V_2 & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{1}{0} & \clr{0}{0} & \clr{0}{0}  \\
V_3 & \clr{1}{1} & \clr{0}{0} & \clr{0}{0} & \clr{0}{1} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} \\
V_4 & \clr{0}{0} & \clr{0}{1} &\clr{0}{0} & \clr{0}{1} & \clr{1}{0} & \clr{1}{0} & \clr{0}{0} \\
V_5 & \clr{0}{1} & \clr{0}{0} & \clr{0}{0} & \clr{0}{1} & \clr{0}{0} & \clr{0}{0} & \clr{1}{0}   \\
V_6 & \clr{0}{0} & \clr{0}{1} & \clr{0}{1} & \clr{0}{0} & \clr{1}{0} & \clr{0}{0} & \clr{0}{0}   \\
V_7 & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0}   \\
\end{block}
\end{blockarray}
\]

\end{document}

这是带有 nicematrix 的矩阵。我添加它只是为了防止添加标题比添加 blockarray 更容易。

\[
\clr {A_1}{A_2}=\begin{pNiceMatrix}[first-row,first-col]
 & V_1& V_2 & V_3 & V_4 & V_5 & V_6 & V_7   \\
V_1 &  \clr{0}{0} &\clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} \\
V_2 & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{1}{0} & \clr{0}{0} & \clr{0}{0}  \\
V_3 & \clr{1}{1} & \clr{0}{0} & \clr{0}{0} & \clr{0}{1} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} \\
V_4 & \clr{0}{0} & \clr{0}{1} &\clr{0}{0} & \clr{0}{1} & \clr{1}{0} & \clr{1}{0} & \clr{0}{0} \\
V_5 & \clr{0}{1} & \clr{0}{0} & \clr{0}{0} & \clr{0}{1} & \clr{0}{0} & \clr{0}{0} & \clr{1}{0}   \\
V_6 & \clr{0}{0} & \clr{0}{1} & \clr{0}{1} & \clr{0}{0} & \clr{1}{0} & \clr{0}{0} & \clr{0}{0}   \\
V_7 & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0} & \clr{0}{0}   \\
\end{pNiceMatrix}

添加

添加xshift两端可以支撑整个矩阵。
