Question

我的谷歌搜索没有提出如何使用算法和算法包在算法中执行switch语句，但我假设你可以。大多数指南都没有提到它。

\begin{algorithm}
\caption{send(...) method}
\begin{algorithmic}
\IF{dest equals..}
%\SWITCH{nature}
\STATE cast data...
\STATE extract data...
\STATE copy...
%\ENDSWITCH
\ELSE
\STATE match dest....
%\SWITCH{nature}
\STATE cast data...
\STATE extract data...
\STATE send...
%\ENDSWITCH
\ENDIF
\end{algorithmic}
\end{algorithm}

谢谢！

我在乳胶文档中写了以下定义。看起来他们的工作。只需在算法包的包含语句后的任何位置插入上面的行。特别是，为了使算法呈现简洁，我区分复合案例和单行案例。单行案例以\ CASELINE开头。复合案例以\ CASE开头，以\ ENDCASE结尾。与默认语句类似。

您可以尝试以下示例。

\SWITCH {$\theta$}
\CASE {1}
  \STATE Hello
\ENDCASE
\CASELINE {2}
  \STATE Good-bye
\DEFAULT
  \STATE Again ?
\ENDDEFAULT
\ENDSWITCH

如果您看一下official documentation from CTAN on the algorithm package，您会注意到，没有默认的SWITCH-CASE语句。我认为这就是原因，为什么它被遗漏在如此多的文件中;）

使用Latex算法包进行switch语句？
