[Tex/LaTex] Right justify columns in border matrix

bordermatrix

I would like to right justify the columns in a border matrix. Is this possible? Default seems to be centre

 \documentclass{article} 
 \begin{document}

    $
     \bordermatrix{~ & 5 & 6\cr
                  5 & 1 & 0 \cr
                  6 & 0 & -1 \cr}
    $
 \end{document}

I don't know if it is possible with bordermatrix, but it is with kbordermatrix by issuing

\kbalignrighttrue

The following lines are to simulate the behavior of bordermatrix

\renewcommand{\kbldelim}{(}
\renewcommand{\kbrdelim}{)}
\renewcommand{\kbrowstyle}{\displaystyle}
\renewcommand{\kbcolstyle}{\displaystyle}

MWE:

\documentclass{article}

\usepackage{kbordermatrix}
\kbalignrighttrue
\renewcommand{\kbldelim}{(}
\renewcommand{\kbrdelim}{)}
\renewcommand{\kbrowstyle}{\displaystyle}
\renewcommand{\kbcolstyle}{\displaystyle}

\begin{document}

    $
     \kbordermatrix{~ & 5 & 6\cr
                  5 & 1 & 0 \cr
                  6 & 0 & -1 \cr}
    $

\end{document}

[Tex/LaTex] How to create a matrix with rows and columns labeled (at the right side)

Here is a way to insert your matrix indices on the top (for columns) and right (for rows):

enter image description here

\documentclass{article}
\usepackage{blkarray}% http://ctan.org/pkg/blkarray
\newcommand{\matindex}[1]{\mbox{\scriptsize#1}}% Matrix index
\begin{document}
\[
  A=\begin{blockarray}{c@{\hspace{5pt}}rr@{\hspace{5pt}}cl}
    & \matindex{1} & \matindex{2} & & \\
    \begin{block}{(c@{\hspace{5pt}}rr@{\hspace{5pt}}c)l}
      & 100 &  b & & \matindex{row 1} \\
      &   2 & 12 & & \matindex{row 2} \\
      &   e &  f & & \matindex{ABDC} \\
    \end{block}
  \end{blockarray}
\]
\end{document}

To improve the spacing between the matrix and the surrounding braces, insert an extra column on either side. Additionally, specify the exact column gap using the @{...} specifier. In the above example, two "dummy" centered columns were added with an \hspace{5pt} gap.

[Tex/LaTex] TikZ-equivalent of bordermatrix with automatic alignment of labels

The result can be achieved by using the OP's code and the linked answers e.g. using:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
\begin{tikzpicture}[baseline = (M.center),% center with respect to the matrix center
        every left delimiter/.style={xshift=1ex},%tighter delimiter spacing
        every right delimiter/.style={xshift=-1ex}]
\matrix (M) [matrix of nodes,left delimiter={(},right delimiter={)},nodes in empty cells 
        ]{ 
                              |[draw,circle,inner sep=3mm,fill]| &  \\
                                & |[draw,circle,inner sep=6mm,fill]|\\
};
\node[anchor=south east, left=6pt] (M-0-0) at (M-1-1.north west) {};
% iterate over each row and their corresponding labels
\foreach[count=\i] \v in {\(A\),\(B\)}{
  % label of this row, based on size of diagonal element
  \node (M-\i-0) at (M-0-0 |- M-\i-\i) {};
  % put the text (specified in the loop) at the label
  \path (M-\i-0.north) -- (M-\i-0.south) node [midway, left] { \v };
}
\end{tikzpicture}
\end{document}

gives
