Appendix- Elsarticle

Question

\documentclass[preprint,review,12pt]{elsarticle}
\begin{document}

\appendix \label{Appendix}
\section{Mass matrix}\label{Mass Matrix}
Blabla ....

\section{Gyroscopic matrix}\label{Gyroscopic Matrix}
Blabla...

\end{document}

I get the following:

Is it possible to have just one appendix without A and B? and How I can refer to the appendix in my text ?

Answer 1

Since you appear to want to create an unnumbered appendix section, the normal \label-\ref cross-referencing mechanism won't do the job. Instead, I suggest you load the hyperref package -- you may already be doing so -- and use that package's \hypertarget-\hyperlink mechanism, as is done in the code below.

\documentclass[preprint,review,12pt]{elsarticle}
\usepackage[colorlinks]{hyperref}
\begin{document}

As will be shown in the \hyperlink{app}{appendix}, \dots

\appendix
\hypertarget{app}{\section*{Appendix. Mass matrix and gyroscopic matrix}}

Blabla \dots

\end{document}
