我怎样才能避免复制和粘贴此代码（使用不同功能的类似新命令定义）：

感谢你们，我一直在改进我的代码，但这看起来仍然可以改进，因为它看起来像一个丑陋的复制/粘贴：

\newcommand*{\LegendFlecheInf}[5]{ 
    \coordinate (C2) at (axis cs:#2, { \FInfAUn(#1,#2) }) ;
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheEga}[5]{ 
    \coordinate (C2) at (axis cs:#2, { \FEgaAUn(#2) }) ;
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheSup}[5]{ 
    \coordinate (C2) at (axis cs:#2, { \FSupAUn(#1,#2) }) ;
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}

这里定义的 3 个命令之间的唯一区别在于将调用哪个函数来计算箭头末端的 y 坐标。

我已经为 MWE 删除了很多内容但它仍然很大：

\documentclass[border=2pt]{standalone}
\usepackage[utf8]{inputenc}

\usepackage{graphics}

\def\FInfAUn(#1,#2){( 1 - ( (exp(-W*#1*#2)/sqrt(1-#1*#1)) *cos((W*#2*sqrt(1-#1*#1) 
                    - (atan(#1/sqrt(1-#1*#1))*pi/180) ) *180/pi) )  ) *\Kg }

\def\FTUn(#1){( 1/( W*(#1-sqrt((#1*#1) -1))) )}
\def\FTDeux(#1){( 1/(W *(#1+sqrt((#1*#1) -1))) )}
\def\FInterSupAUn(#1,#2,#3){(  \Kg * (1 - ( 1/( #1 - #2 ) )*( #1 *exp(-#3/ #1 ) - #2 *exp(-#3/ #2 ) ))   )}

    \newcommand*{\LegendFlecheInf}[5]{ 
        \coordinate (C2) at (axis cs:#2, { \FInfAUn(#1,#2) }) ;
        \draw node[anchor=#3] (#4) at #5 {$z =#1$};
        \draw[fleche] (C2) -- (#4.west) ;
    }
    \newcommand*{\LegendFlecheEga}[5]{ 
        \coordinate (C2) at (axis cs:#2, { \FEgaAUn(#2) }) ;
        \draw node[anchor=#3] (#4) at #5 {$z =#1$};
        \draw[fleche] (C2) -- (#4.west) ;
    }
    \newcommand*{\LegendFlecheSup}[5]{ 
        \coordinate (C2) at (axis cs:#2, { \FSupAUn(#1,#2) }) ;
        \draw node[anchor=#3] (#4) at #5 {$z =#1$};
        \draw[fleche] (C2) -- (#4.west) ;
    }

你可以更换

\newcommand*{\LegendFlecheInf}[5]{ 
    \coordinate (C2) at (axis cs:#2, { \FInfAUn(#1,#2) }) ;
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheEga}[5]{ 
    \coordinate (C2) at (axis cs:#2, { \FEgaAUn(#2) }) ;
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheSup}[5]{ 
    \coordinate (C2) at (axis cs:#2, { \FSupAUn(#1,#2) }) ;
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}

经过

\newcommand*{\Legendx}[6]{ 
    \coordinate (C2) at (axis cs:#2, { #6(#1,#2) }) ;
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}

然后替换例如

\LegendFlecheEga{1}{0.6}{south}{C5}{(C4.north)}

经过

\Legendx{1}{0.6}{south}{C5}{(C4.north)}\FEgaAUn

答案2

利用该ifthen软件包，您可以用一个新命令替换这三个命令：

\newcommand{\LegendComplex}[6]{  
     \ifthenelse{\equal{#6}{inf}}{\coordinate (C2) at (axis cs:#2, {\FInfAUn(#1,#2)});}{}
     \ifthenelse{\equal{#6}{sup}}{\coordinate (C2) at (axis cs:#2, {\FSupAUn(#1,#2)});}{}
     \ifthenelse{\equal{#6}{ega}}{\coordinate (C2) at (axis cs:#2, {\FEgaAUn(#2)});}{}      
    \draw node[anchor=#3] (#4) at #5 {$z =#1$};
    \draw[fleche] (C2) -- (#4.west) ;
}

您必须提供一个新参数（sup、inf 或 ega）来指定您想要调用哪个函数。
