You have a fair number of choices. Here's one option using the array environment from amsmath:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
R = \left(
\begin{array}{@{}ccccc@{}}
1 & 1 & 2 & 3 & 7 \\
3 & 1 & 4 & 4 & 0 \\
\end{array}
\right) ;
\]
\end{document}

You might want to consult the mathmode document for simple tasks like this.

Another solution with the amsmath package.

Code: Select all

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}

\begin{document}
  \[
    R= 
    \begin{pmatrix}
      1 & 1 & 2 & 3 & 7 \\
      3 & 1 & 4 & 4 & 0
    \end{pmatrix};
  \]

  The in-line version looks like
  \(
    R=\bigl( 
    \begin{smallmatrix}
      1 & 1 & 2 & 3 & 7 \\
      3 & 1 & 4 & 4 & 0
    \end{smallmatrix}
    \bigr)
  \).
\end{document}

Further enhancements are possible with the mathtools package from the mh bundle.

By the way, the array environment comes from vanilla LaTeX.
