我已经安装了完整的 mtpro2,其mtpro2.sty
内容如下:
\NeedsTeXFormat{LaTeX2e}[1997/06/01]
\ProvidesPackage{mtpro2}
[2009/4/27 v2.3
MathTimePro II - added arc accents
MathTimePro II - fixed rbrace problem with straightbraces and morphedbraces options
MathTimePro II - fix bug with z = \backslash widetilde{\backslash sum_{x }}%
MathTimePro II v2 font support (PCTeX/WaS)%
MathTimePro II v2.1a Allowed alternate form of I in Math Script Fonts (MS)%
]
morphedbraces
但是,当我使用带有以下选项的包时:
\documentclass{article}
\usepackage{amsmath}
\usepackage[morphedbraces]{mtpro2}
\begin{document}
\[
\left\{\right\} \quad \Bigl\{\Bigr\} \quad
\left\{\begin{matrix} 1 \\ 2 \\ 3 \\ 4 \\ 5 \\ 6 \end{matrix} \right\} \quad
\left\{\frac12\right\}
\]
\end{document}
如果我使用该straightbraces
选项,异常会再次发生:
如何解决这个问题?
