Math & Science ⇒ Text alignment in array environment

[Dominique]

Hey everyone,

I want to make a scale that looks like the one at the top of page 8 of this article: http://ricknouwen.org/rwfn/wp-content/u ... -round.pdf and I've succeeded in creating large square brackets but I can't figure out how to get the gamma between the "alpha-line" and the "beta-line". Right now there is a line between alpha and beta and I don't like the way that looks. This is the code I used:

Code: Select all

$\left< \begin{array}{cc}
\alpha \\  & \gamma \\ \beta \end{array} \right>$

Can anyone help me out?

Thanks in advance!

There might be better ways but here's an idea:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\newcommand\AoverB[2]{\genfrac{}{}{0pt}{}{#1}{#2}}
\begin{document}

\[
\Biggl\langle \quad \AoverB{\alpha}{\beta} \quad \gamma \quad\Biggr\rangle
\]

\end{document}

You can find details about \genfrac in amsmath or mathmode.

That looks great; thank you very much!
