子图有问题吗？

作为 LaTeX 的新手，我目前正在准备我的第一篇论文。因为我要提交论文的会议要求作者使用IEEE 会议论文模板。

我在子图方面遇到了问题。以下是我的代码。

\section{Conclusion}
% An example of a double column floating figure using two subfigures.
% (The subfig.sty package must be loaded for this to work.)
% The subfigure \label commands are set within each subfloat command, the
% \label for the overall figure must come after \caption.
% \hfil must be used as a separator to get equal spacing.
% The subfigure.sty package works much the same way, except \subfigure is
% used instead of \subfloat.

\begin{figure*}[!t]
\centerline{\subfloat[Case I]\includegraphics[width=2.5in]{subfigcase1}%

错误消息：

! Undefined control sequence.<argument> \subfloat[Case I]\includegraphics [width=2.5in]{subfigcase1}\lab... \label{fig_first_case}}

Label `fig_sim' multiply defined.
There were multiply-defined labels.

我哪里做错了？

您在子图的语法上犯了一些小错误。替换 »子图“ 经过 ”子图« 采用以下方式起作用。

\documentclass[conference]{IEEEtran}
\usepackage[T1]{fontenc}
\usepackage[demo]{graphicx}  % drop `demo` option in actual document!
\usepackage[caption=false]{subfig}

请注意，图将移至下一页。
