自动将方程式的详细信息放入附录中

自动将方程式的详细信息放入附录中

我如何才能自动将有关某个方程的详细信息放入附录中？

我尝试过回答取得了一些成功。但是，我希望这些数字可以作为可点击的交叉引用，就像我\ref{something}在包中使用内部文本时一样hyperref。

例如：

        2x(3+3)=12             (1.1)
    details: see page (clickable)123

附录中：

    details of equation (clickable)1.1:
         2x(3+3)
        =2x3+2x3
        =6+6
        =12

答案1

这和在不同的地方写问题和答案非常相似；我非常喜欢answers包，这是我在下面的解决方案中所使用的。

步进计数器有点笨拙（也许有人会有改进的建议），但我认为它能满足你的要求。

\documentclass{article}

\usepackage{lipsum}     % for sample text
\usepackage{amsmath}    % for mathematical environments
\usepackage{answers}    % for file writing
\usepackage{etoolbox}   % for \AtBeginEnvironment (and a lot more)
\usepackage{hyperref}   % for hyperlinks- load it last

% hyperlinks
\hypersetup{colorlinks=true,
linkcolor=blue}

% very useful during de-bugging!
%\usepackage[left]{showlabels}
%\showlabels{hypertarget}
%\showlabels{hyperlink}

% appendix file
\Opensolutionfile{appendixmaterial}
\Newassociation{appmat}{appMAT}{appendixmaterial}

% setup hypertargets for equations
\AtBeginEnvironment{equation}{%
\stepcounter{equation}%
\hypertarget{q:myref\theequation}{}%
\Writetofile{appendixmaterial}{\protect\hypertarget{a:myref\theequation}{}}%
\Writetofile{appendixmaterial}{\protect\label{a:myref\theequation}{}}%
\addtocounter{equation}{-1}%
}

% command to link to the appendix
\newcommand{\linktoappmat}{%
details of equation \hyperlink{a:myref\theequation}{\theequation} (see page \pageref{a:myref\theequation})}

\begin{document}

    2\cdot (3+3)=12   
    \begin{appmat}
     \begin{align*}
     2\cdot (3+3)   & =2\cdot 3+2\cdot 3   \\
                    &=6+6       \\
                    & =12       \\
     \end{align*}
    \end{appmat}
\end{equation}
\linktoappmat
\begin{equation}

    \begin{appmat}
     \begin{align*}

                    &=10+10       \\
                    & =20       \\
     \end{align*}
    \end{appmat}
\end{equation}
\linktoappmat


% close solution file
\Closesolutionfile{appendixmaterial}

% renew the solution environment so that it hyperlinks back to 
% the question
\renewenvironment{appMAT}[1]{%
         % add some glue
         \vskip .5cm plus 2cm minus 0.1cm%
         {details of equation \bfseries \hyperlink{q:myref#1}{#1.}}%
}%
{%

\clearpage

% input the file if it exists
\IfFileExists{appendixmaterial.tex}{\input{appendixmaterial.tex}}{}
\end{document}

答案2

受到上述答案的启发。我调整了步进计数器等一些东西，并添加了一个条件，因此附录中的解决方案按章节分开。它并不完美，但可以按预期工作。谢谢@cmhughes。
