I want to use subfig to put multiple pictures under one caption. However, the error mentioned in the title occurs.

\documentclass[conference]{IEEEtran}
\usepackage{cite}
%\usepackage{caption}
%\usepackage[font=footnotesize]{subfig}
\usepackage{subfig}
\usepackage{url}
\usepackage{amssymb}
\usepackage{amsmath}

\newcommand{\sH}{{\sf H}}
\newcommand{\veceps}{{\boldsymbol{\varepsilon}}}
\newcommand{\isdef}{\stackrel{\rm def}{=}}

\newtheorem{theorem}{Theorem}

\newtheorem{corollary}[theorem]{Corollary}

Best Answer

Add \usepackage{graphicx} to your preamble. You also have a stray } after your \end{figure}. Fix those two things and you'll be on your way!
