如何在 latex 中写出 L 形符号？

我想在乳胶中写下以下等式，但不知道那个 L 形符号是什么。 在此处输入图片描述

我尝试了“\llcorner”，但这不是我真正想要的......它看起来像下面的图像： 在此处输入图片描述

我也试过数学家并阅读很棒的乳胶符号大列表，但找不到。因此，任何帮助都非常感谢。

答案1

它可以由 s 构建\rule。

\documentclass{article}
\usepackage{mathtools}
\usepackage[scr=boondoxupr]{mathalpha}
\newcommand*{\Lcorner}{%
    \mathchoice%
        {\mathrel{\makebox[7pt][c]{\rule{.4pt}{7.5pt}\rule{5pt}{.4pt}}}}%
        {\mathrel{\makebox[7pt][c]{\rule{.4pt}{7.5pt}\rule{5pt}{.4pt}}}}%
        {\mathrel{\makebox[5.5pt][c]{\rule{.4pt}{5.25pt}\rule{3.5pt}{.4pt}}}}%
        {\mathrel{\makebox[4pt][c]{\rule{.4pt}{3.75pt}\rule{2.5pt}{.4pt}}}}%
}
\DeclareMathOperator{\Tan}{Tan}

\begin{document}
\(\displaystyle \Lcorner\)
\(\textstyle \Lcorner\)
\(\scriptstyle \Lcorner\)
\(\scriptscriptstyle \Lcorner\)

\(\displaystyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)

\(\textstyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)

\(\scriptstyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)

\(\scriptscriptstyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)
\end{document}

答案2

符号为，并且在或旧版软件包、、、和一些其他软件包\rightangle中为。unicode-mathstixstix2mathdesignfdsymbol

答案3

图片模式来拯救你。符号在各种数学样式以及不同字体大小下都能正确改变大小。

\documentclass{article}
\usepackage{amsmath,pict2e,mathrsfs}

\makeatletter
\DeclareRobustCommand{\Lcorner}{\mathbin{\mspace{1mu}\text{\L@corner}\mspace{1mu}}}
\newcommand{\L@corner}{%
  \setlength{\unitlength}{\fontcharht\font`T}%
  \begin{picture}(0.8,1)
  \roundcap
  \Line(0,1)(0,0)(0.8,0)
  \end{picture}%
}
\makeatother

\DeclareMathOperator{\Tan}{Tan}

\begin{document}

\(\displaystyle \Lcorner\)
\(\textstyle \Lcorner\)
\(\scriptstyle \Lcorner\)
\(\scriptscriptstyle \Lcorner\)

\(\displaystyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)

\(\textstyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)

\(\scriptstyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)

\(\scriptscriptstyle \Tan^k( \mathscr{H}^k \Lcorner F(E), y ) = DF(x)[\Tan^k( \mathscr{H}^k \Lcorner E, x)]\)

{\Large $A\Lcorner B$} {\footnotesize $A\Lcorner B$}
\end{document}

我重复使用了文森特编写的代码。
