![我如何消除“\choose”错误?](https://linux22.com/image/368745/%E6%88%91%E5%A6%82%E4%BD%95%E6%B6%88%E9%99%A4%E2%80%9C%5Cchoose%E2%80%9D%E9%94%99%E8%AF%AF%EF%BC%9F.png)
此代码
\begin{equation}
\sum_{j=1}^{Max\_out}{M' \choose j}.
\end{equation}
产生错误:
Package amsmath Warning: Foreign command \atopwithdelims;
(amsmath) \frac or \genfrac should be used instead
(amsmath) on input line 229
奇怪的是,方程之外不存在这样的误差,该误差仅出现在方程内部。
我该如何修复它?
