This question already has an answer here:

So i created a matrix in latex using the code:

\usepackage{kbordermatrix}
\usepackage{blkarray
\renewcommand{\kbldelim}{(}% Left delimiter
\renewcommand{\kbrdelim}{)}% Right delimiter
\[
   \kbordermatrix{
    & a & b & c & d\\
    a & 2173.00 & 354.00 & 0.00 & 1249.00 \\
    b & 0.00 & 3772.00 & 52.00 & 0.00 \\
    c & 474.00 & 469.00 & 2858.00 & 42.00 \\
    d & 1262.00 & 303.00 & 39.00 & 2180.00\\
  } 
\]

The above code is taken from here The output matrix which I got is this: enter image description here

My doubt lies in my next task. I want to put a row of labels below my matrix like: enter image description here

How can i achieve this?

Thanks.

    From the kbordermatrix docs: I also have an experimental version that will put the labels on the right and bottom. If you ask, I will make it available. I might even try to make a version that lets you specify the layout, but I am content with top and left. – percusse Oct 2 '16 at 22:45
  • @percusse It would be really helpful if you can make it available. I need the labels below the matrix – Jishan Oct 2 '16 at 22:47
  • percusse is only quoting from the documentation, but is not the author. You have to contact Kim C Border, kcb@caltech.edu – gernot Oct 2 '16 at 23:08

With blockarray the parentheses have a tendency to be too small, but it's easy to coerce them to be a bit larger.

\documentclass{article}
\usepackage{amsmath,blkarray}

\begin{document}

\[
\begin{blockarray}{ccccc}
\begin{block}{c(cccc)}
a & 2173.00 & 354.00 & 0.00 & 1249.00\smash[b]{\vphantom{\Big|}} \\
b & 0.00 & 3772.00 & 52.00 & 0.00 \\
c & 474.00 & 469.00 & 2858.00 & 42.00 \\
d & 1262.00 & 303.00 & 39.00 & 2180.00\smash[t]{\vphantom{\Big|}}\\
\end{block}
& a & b & c & d
\end{blockarray}
\]

\end{document}
