乳胶中的高级箭头

Question

latex 中是否有包含以下箭头命令的包？

Answer 1

集合mathb中mathabx有dlsh命令。以下是如何在不更改数学字体的情况下借用它：

\documentclass[11pt]{article}

\DeclareFontFamily{U}{mathb}{\hyphenchar\font45}
\DeclareFontShape{U}{mathb}{m}{n}{%
 <-6> mathb5
<6-7> mathb6
<7-8> mathb7
<8-9> mathb8
<9-10> mathb9
 <10-12> mathb10
  <12-> mathb12
  } {}%
\DeclareSymbolFont{mathb}{U}{mathb}{m}{n}

\DeclareMathSymbol{\dlsh}{\mathrel}{mathb}{"EA}

\begin{document}

\[ X \dlsh Y\]%

\end{document}
