How can I capitalize the first letter while using '\cref'? [closed]

Question

I use package cleveref to refercence a figure or table in latex.

\usepackage{hyperref}
\usepackage{cleveref}

\cref{sim_figure}

The result is some like fig. 1, table I.

However, my expected result is Fig. 1 or Table I which is required by IEEEtran. How can I capitalize the first letter?

Answer 1

This is clearly outlines in the cleveref documentation.

You can either use \Cref, or pass the package option capitalise:

\documentclass{ieeetran}
\usepackage{hyperref}
\usepackage[capitalise]{cleveref}
\begin{document}
See \cref{fig:myfigure} or \Cref{fig:myfigure}.
\begin{figure}
  \caption{Some figure}\label{fig:myfigure}
\end{figure}
\end{document}

If you wish to customize the way \Cref prints (output Fig. rather than Figure), add

\Crefname{figure}{Fig.}{Figs.}% {<type>}{<singular>}{<plural>}
