How can I create a vector like this one?
It is similar to this question, but with additional columns.

The precise output depends on the desired packages ;-)– user31729Oct 8, 2014 at 16:39

Quick and dirty approach with pmatrix environment
The individual columns are separated by a & character, the next linebreak is achieved with \\
If one replaces pmatrix with bmatrix, the [ ] version is obtained
\documentclass[12pt]{article}
\usepackage{mathtools}
\begin{document}
\begin{equation*}
A = \begin{pmatrix}
3 & 5 \\
5 & 2 \\
2 & 1 \\
1 & 4 \\
7 & 9
\end{pmatrix}
\end{equation*}
\end{document}

1@ChristianHupfer Can you tell me where in the LaTeX manual or the doc for
amsmaththere's a description of\cr? Possibly I didn't read them carefully enough. Out of joke: DON'T use\crin LaTeX documents.– egregOct 8, 2014 at 17:55 -
1@ChristianHupfer It's not “old style”: it's wrong. You may have seen
\matrix{1 & 2\cr 3 & 4\cr}using the LaTeX command inherited from Plain, that's supplanted bymatrixofamsmath(and the other environments adding parentheses). See tex.stackexchange.com/questions/57658/…– egregOct 8, 2014 at 18:04
