I decided to combine two adjacency matrices into one in order to save space.
However, how can I add the vertex names to the matrix?
Also please suggest if you have any idea to improve or better way to show the two adjacency matrices.

enter image description here

\documentclass[journal]{IEEEtran}
\usepackage{graphicx}
\usepackage{mathtools}
\usepackage{xcolor}

\begin{document}


$\textcolor{red}{A_{1}}/\textcolor{blue}{A_{2}}=\begin{pmatrix}
    \textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}\
    \textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}\
    \textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}\
    \textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{1}\
    \textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}&\textcolor{red}{0}/\textcolor{blue}{1}\
    \textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{1}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}&\textcolor{red}{0}/\textcolor{blue}{0}\
\end{pmatrix}$
\end{document}

  • One easy way is to use nicematrix. A quick search should give you hints (or even a solution) – SebGlav Sep 15 '22 at 17:08
  • @SebGlav I'll check if it works. Btw, do you have any idea to simpify the code with \textcolor{red}{}/\textcolor{blue}{}? I think it's possible to make a command for this. – hana Sep 15 '22 at 17:23

    Do this: \newcommand{\clr}[2]{\textcolor{red}{#1}/\textcolor{blue}{#2}}, then call it like this: \clr{0}{1}. The name \clr can be changed to whatever you want. – SebGlav Sep 15 '22 at 17:52
