I'm trying to achieve left and right brace math delimiters, the ones that LaTeX has as standard, since I don't really like the ones that mathdesign
font has. Is there some command such as \definemathdelimiter
to redefine it?
\documentclass[12pt]{article}
\usepackage[charter]{mathdesign}
\usepackage{amsmath}
\usepackage{abraces}
\begin{document}
\begin{equation*}
\phi(z) =
\left\{\begin{tabular}{cl}
$ 2\arctan\left(\dfrac{y}{\sqrt{x^2+y^2} + x}\right) $ & if $ x>0 \text{ or } y \neq 0 $\\
$ \pi $ & if $ x<0\text{ and } y = 0 $ \\
Does not exist & if $ x=0\text{ and } y = 0 $
\end{tabular}\right.\
\end{equation*}
\[
\aunderbrace{\text{The desired delimiter}}
\]
\end{document}
