Please help me to produce this matrix with LaTeX. I tried this:
\documentclass{article} \usepackage{amsmath} \usepackage{mleftright} \begin{document} [ \renewcommand\arraystretch{1.3} \mleft[ \begin{array}{c|c|c|c} \ 0 2 2 \dots 2 \\ 202\dots2 \\ \\ \\ \\ 222 \dots 0 & 111 & \dots & 11 \\ \hline \ 111\dots 1 \\ 111\dots 1 \\ 111 \dots 1 & 022 \ & \dots & 11 \\ \end{array} \mright] ] \end{document} But it doesn't come out exactly right.
Like this?
\documentclass{article} \usepackage{amsmath} \usepackage{mleftright} \usepackage{array, multirow} \usepackage[svgnames, table]{xcolor} \begin{document} \[ \renewcommand\arraystretch{1.3} \arrayrulecolor{Silver!80} \mleft[ \begin{array}{*{5}{c}|ccc|c|cc} 0 & 2 & 2 & \dots & 2 & 1 & 1 & 1 & \multirow{4}{*}[-1ex]{\dots }& 1 & 1\\ 2 & 0 & 2 & \dots & 2 & 1 & 1 & 1 & & 1 & 1 \\ \vdots & & & & & & & & & & \vdots\\ 2 & 2 & 2 & \dots & 0 & 1 & 1 & 1 & & 1 & 1 \\ \hline 1 & 1 & 1 & \dots & 1& 0 & 2 & 2 & & 1 & 1 \\ 1 & 1 & 1 & \dots & 1& 2 & 0 & 2 & \dots & 1 & 1 \\ 1 & 1 & 1 & \dots & 1& 2 & 2 & 0 && 1 & 1 \end{array} \mright] \] \end{document}
