  • I have added the code in which tried by me. in this i am unable to fix the row line and column line from first row to last row and first column to last one. – user51868 Jun 27 '17 at 15:28
  • Fix how exactly? – Bernard Jun 27 '17 at 15:39
  • Do you really want the numbers 1 2 3 4 5 6 as in the picture, not in line with the columns of the matrix? What do they mean? – Benjamin McKay Jun 27 '17 at 15:41
  • I need that it will appear above the first column (top border – user51868 Jun 27 '17 at 15:47

Here is a way to obtain it with blkarray and pstricks. I added auto-pst-pdf to compile with pdflatex, but this requires to launch the compiler with the enable-write18 switch (MiKTeX) or -shell-escape (TeX Live, MacTeX):

\documentclass[12pt, svgnames]{article}
\usepackage[utf8]{inputenc}
\usepackage{blkarray, bigstrut, amsmath}
\usepackage{pst-node, auto-pst-pdf}
\begin{document}

\[ \begin{postscript}
    \begin{blockarray}{c*{6}{c}}
      \begin{block}{c*{6}{>{$ \footnotesize $}c}}
        & \thead{1} & \thead{2} & \thead{3} & \thead{4} & \thead{5} & \thead{6} \\
      \end{block}
      \begin{block}{>{\footnotesize }c(*{6}{c})}
        1 & \rnode{A}{1.5} & 3.5 & 1 & (1) & \Rnode{E}{1} & \rnode{B}{4}\bigstrut[t] \\
        2 & 1.8 & (1) & 3.1 & 2.6 & 1.9 & 1.8 \\
        3 & (1) & 1 & 1 & 1.4 & 1.1 & 2.1 \\
        4 & 3.8 & 4 & (1) & 5.6 & 2.8 & 2.2 \\
        5 & 3 & 3.3 & 1 & 4.6 & 4.6 & 5 \\
        6 & \Rnode{D}{4.8} & 4.9 & 3.2 & 5.5 & \Rnode{F}{2.8} & \Rnode{C}{(1)}\bigstrut[b] \\
      \end{block}
    \end{blockarray}
    \psset{linewidth=0.4pt, linecolor=LightSteelBlue, nodesep = -1.4em}
    \ncline[nodesepB=-.8em]{A}{B}
    \ncline{C}{D}
    \psset{nodesep=-1em}
    \ncline{A}{D}
    \ncline{B}{C}
    \ncline{E}{F}
  \end{postscript} \]

\end{document}
