Undefined control sequence. \section

"Undefined control sequence. \section"是一个LaTeX编译错误，表示在代码中使用了未定义的命令"\section"。这个错误通常出现在忘记加载相应宏包或者输入错误命令时。解决方法是删除文件夹中对应的".aux"文件，然后重新编译。如果问题仍然存在，可以尝试删除对应的".bll"文件，再次编译。如果问题仍未解决，可能是因为忘记引入某个宏包。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
