[Tex/LaTex] How to make a IEEE cross-reference

ieeetran

The IEEE cross-reference notation is [1, Fig. 2] that means “in Fig. 2 of reference [1]”, how to make this one in my latex.

My code:

\begin{filecontents*}{test.bib}
@article{ugrinovskii13,
doi = {10.1109/tac.2013.2256675},
author={Valery Ugrinovskii},
volume = {58},
number = {10},
pages = {2659-2664},
title = {Conditions for Detectability in Distributed Consensus-Based Observer       Networks},
journal ={IEEE trans. Automat. Contr.}
 }
\end{filecontents*}

    \documentclass{article}
\usepackage{cite}
\usepackage{url}

\begin{document}
Fig. 2 of  \cite{ugrinovskii13}

\bibliographystyle{IEEEtran}
\bibliography{test}
\end{document}

Best Answer

As suggested by @Mico, I solved this problem, just \usepackage{cite}, then, \cite[Fig.~2]{ugrinovskii13}, everything is fine now.

\begin{filecontents*}{test.bib}
@article{ugrinovskii13,
doi = {10.1109/tac.2013.2256675},
author={Valery Ugrinovskii},
volume = {58},
number = {10},
pages = {2659-2664},
title = {Conditions for Detectability in Distributed Consensus-Based Observer          Networks},
journal ={IEEE trans. Automat. Contr.}
}
\end{filecontents*}

\documentclass{article}
\usepackage{cite}
\usepackage{url}

\begin{document}
\cite[Fig.~2]{ugrinovskii13}

\bibliographystyle{IEEEtran}
\bibliography{test}
\end{document}

The output is
