![将文本放置在案例环境中](https://linux22.com/image/468136/%E5%B0%86%E6%96%87%E6%9C%AC%E6%94%BE%E7%BD%AE%E5%9C%A8%E6%A1%88%E4%BE%8B%E7%8E%AF%E5%A2%83%E4%B8%AD.png)
我怎样才能将文本放在(a case)
最后一个括号的末尾?
\begin{align}
P_{12}=
\begin{cases}
\begin{split}
-\biggl(\left [ \text{Some expression here} \right ]\\-\left [ \text{Some expression here}\right ]\biggr)
\end{split}
\text{a case}
\end{cases}
\end{align}
答案1
以下情况之一 [双关语]?我不清楚您是否要将“一个案例”和“另一个案例”垂直居中放置或放置在表达式的左下方。
\documentclass{article} % or some other suitable document class
\usepackage{mathtools} % for 'dcases' env.
\begin{document}
\begin{equation}
P_{12}=
\begin{dcases}
\begin{aligned}
-\Bigl( [ \text{Some expression here}]& \\
- [ \text{Some expression here}]& \Bigr)
\end{aligned}
& \text{a case} \\[3ex]
\begin{aligned}[b]
-\Bigl( [ \text{Some expression here}]& \\
- [ \text{Some expression here}]& \Bigr)
\end{aligned}
& \text{another case}
\end{dcases}
\end{equation}
\end{document}
