General ⇒ need no Appendix numbering

[pallav]

I have a problem with my appendix. Actually, no numbering of appendix is needed and all of my equations of the appendix section should be numbered as (A.1), (A.2). The second is coming OK but Appendix section is numbered by 1, which I don't want. Note that \section*{Appendix} does not solve the issue (equation numbering is not desirable for it).

Note that I have one and only one Appendix section.

Please be kind enough to help me to solve the problem.

I need no numbering of appendix and I need all equations of the appendix section numbered as (A.1), (A.2).[…]

Don't you think that this is quite irritating for the reader?

Yes, I understand the language problem. I have edited. Very sorry for the inconvenience caused due to the fact.

Of course I understood what you wanted to say. Actually I meant that it could be irritating for the reader of your document to have an unnumbered appendix but strangely numbered equations.

[pallav]

Yes, I got your point.

[localghost]

Yes, I got your point.

And you want to keep that numbering or not?

[pallav]

Equation numbering in a presentable way is earnestly solicited. Also, as I have only one appendix section, I don't want to mention this section as appendix A. Please help me to solve this issue so that I can present the appendix along with its equation numbering in a most presentable way.

Try this sample with a customization by titlesec. I ventured to optimize parts of the code. Furthermore I shortened the example by cutting irrelevant code (which is not needed at all) to make it more minimal.

\documentclass[final,3p,times]{elsarticle}
\usepackage[T1]{fontenc}
\usepackage{mathtools}  % loads »amsmath«
\usepackage{amssymb,amsfonts,amsthm}

\usepackage[raggedright]{titlesec}
\titleformat{\section}{\normalfont\bfseries}{\thesection.}{1em}{}

\usepackage{hyperref}
\hypersetup{
  colorlinks=true,
  linkcolor=blue,
  anchorcolor=blue,
  citecolor=blue,
  pdfstartpage=1,
  filecolor=red,
  urlcolor=red
}

\numberwithin{equation}{section}
\biboptions{comma,square,sort&compress}

\begin{document}
  \section{Introduction}\label{sec:intro} 
    \noindent Study 
    \begin{align}
      a=b+c
    \end{align}

  \section{abs}
    Let
    \begin{align}
      c=d+r
    \end{align}

  \titleformat{\section}{\normalfont\bfseries}{}{0em}{}
  \appendix
  \section{Appendix}
    \noindent \textbf{Computation of A, B, C}
    \vspace{2em}

    \noindent Throughout this section,
    \begin{align}
       A=a+b+c
    \end{align}
\end{document}

Remarks:

• There will be a warning from titlesec which can be neglected as everything works as expected.

Thanks a lot. Its works fine.
