标题Re: [问题] equation换行的括号问题
时间Thu Dec 11 07:27:16 2008
※ 引述《g9661527 (...)》之铭言：
: 假设想排出下式
: 1
: a = {－
: 2
: + b }
: ---------------------------------------------
: \usepackage{amsmath}
: \begin{align}
: a = & \left\{ \frac{1}{2} \right. \\
: & \left. + b \right\}
: \end{align}
: ----------------------------------------------
: 以上会让上下两个括号大小不一样
: 但是如果把 \right. 和 \left. 去掉的话会出错
: 请问有什麽办法可以让上下两个括号大小一样吗？
: 谢谢，感激不尽
a = & \left\{ \frac{1}{2} \right. \\
& \left. + b \vphantom{\frac 1 2}\right\}
