Math & Science ⇒ incorrect size of parentheses in pmatrix environment

[stpasha]

I need to set the double inter-line spacing in the entire documents, so I just set the \baselinestretch variable appropriately. However this command seems to interfere with the *matrix environments: the braces surrounding the matrices become too large, with some extraneous spacing at the top and at the bottom. Does anybody have any suggestions how to fix this behavior? Ideally, I'd like the *matrix environment behave as if the \baselinestretch was 1.0-1.2.

Code: Select all

\documentclass{article}
\renewcommand{\baselinestretch}{1.5}
\usepackage{amsmath}
\begin{document}
  \[
  \begin{pmatrix} z \\ \bar{z} \end{pmatrix}
  \]
\end{document}

Read Section 1.4 (Changing inter-line space using \baselinestretch, p. 5) of the l2tabu document to learn why not to redefine this length. Use one of the introduced alternatives instead.

Code: Select all

\documentclass[11pt,a4paper,english]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage[onehalfspacing]{setspace}
\usepackage{amsmath}
\usepackage{blindtext}

\begin{document}
  \blindtext
  \[
    \begin{pmatrix}
      z \\
      \bar{z}
    \end{pmatrix}
  \]
\end{document}

The blindtext package is only for creating dummy text thus not part of the solution.

Thanks --- the {setspace} package helped.
