如何在 LateX 上绘制此图？

Question

我需要能够在 LateX 或 maple 或 tikz 中写出这个。

Answer 1

希望这能为你提供足够的信息来帮助你入门

\documentclass[tikz, border = 4pt]{standalone}

\begin{document}
\begin{tikzpicture}
  \foreach \i in {1,...,5} {
    \foreach \j in {1,...,\i} {
      \draw (\i, \j) rectangle (\i + 1, \j + 1);
    }
  }
\end{tikzpicture}
\end{document}

Answer 2

这些东西很容易让人联想到杨的画作，那么为什么不在这里使用它们呢？

 \documentclass{article}
 \usepackage{young}
 \usepackage{tikz}
 \usetikzlibrary{calc}
 \newcommand{\tikznode}[2]{\tikz[remember picture,baseline=(#1.base),inner
 sep=0pt]{\node(#1)[inner sep=0pt]{#2};}}
 \begin{document}
 \[
 \begin{tabular}{l}
 \begin{Young}
  & & & & \cr
  & & & \cr
  ~& ~& \tikznode{13}{~} \cr
  ~& \tikznode{12}{~}\cr
  \tikznode{11}{~} \cr
 \end{Young}\\[1cm]
 \begin{Young}
  \tikznode{21}{~} &  \tikznode{22}{~}& \tikznode{23}{~} \cr
   & & \cr
  \tikznode{24}{~} & \tikznode{25}{~}\cr
 \end{Young}\\[1cm]
 \begin{Young}
  \tikznode{31}{~} &  \tikznode{32}{~}\cr
  \tikznode{33}{~}\cr
 \end{Young}\\[1cm]
 \begin{Young}
  \tikznode{41}{~}\cr
 \end{Young}
 \end{tabular}
 \]
 \begin{tikzpicture}[overlay,remember picture]
 \foreach \X/\Y in {11/21,12/22,13/23,24/31,25/32,33/41}
 \draw[thick,-latex] ($(\X.south)-(0,2pt)$)--($(\Y.north)+(0,8pt)$);
 \end{tikzpicture}
 \end{document}

Answer 3

忘记tikz。 堆叠它！ 这里，\sq为正方形，\vl为垂直线段，\ah为向下指向的箭头。

\documentclass{article}
\usepackage{graphicx,amssymb}
\usepackage[usestackEOL]{stackengine}
\newcommand\sq{\framebox(10,10){}\kern\fboxrule}
\newcommand\vl{\rule{0pt}{10pt}\makebox[\dimexpr10pt+\fboxrule]{%
  \smash{\rule[0\fboxrule]{\fboxrule}{\dimexpr10pt+\fboxrule}}}}
\newcommand\ah{\smash{\makebox[\dimexpr10pt+\fboxrule]{\raisebox{3pt}{%
  \scalebox{.5}[-.5]{$\blacktriangle$}}}}}
\def\stackalignment{l}
\setstackgap{S}{\fboxrule}
\begin{document}
\Shortunderstack{\sq\sq\sq\sq\sq\\\sq\sq\sq\sq\\\sq\sq\sq\\\sq\sq\vl\\%
  \sq\vl\vl\\\vl\vl\vl\\\ah\ah\ah\\\sq\sq\sq\\\sq\sq\sq\\\sq\sq\\\vl\vl\\%
  \vl\vl\\\ah\ah\\\sq\sq\\\sq\\\vl\\\ah\\\sq}
\end{document}

如果想要一个可以方便地更改网格大小和箭头大小的版本，请参阅\gs下面\as的 MWE 中的定义。

\documentclass{article}
\usepackage{graphicx,amssymb}
\usepackage[usestackEOL]{stackengine}
\newcommand\gs{10}% GRID SIZE (pts)
\newcommand\as{.5}% ARROW SCALE
\newcommand\sq{\framebox(\gs,\gs){}\kern\fboxrule}
\newcommand\vl{\rule{0pt}{\gs pt}\makebox[\dimexpr\gs pt+\fboxrule]{%
  \smash{\rule[0\fboxrule]{\fboxrule}{\dimexpr\gs pt+\fboxrule}}}}
\newcommand\ah{\smash{\makebox[\dimexpr\gs pt+\fboxrule]{%
  \scalebox{\as}[-\as]{\raisebox{-1.3ex}{$\blacktriangle$}}}}}
\def\stackalignment{l}
\setstackgap{S}{\fboxrule}
\begin{document}
\Shortunderstack{\sq\sq\sq\sq\sq\\\sq\sq\sq\sq\\\sq\sq\sq\\\sq\sq\vl\\%
  \sq\vl\vl\\\vl\vl\vl\\\ah\ah\ah\\\sq\sq\sq\\\sq\sq\sq\\\sq\sq\\\vl\vl\\%
  \vl\vl\\\ah\ah\\\sq\sq\\\sq\\\vl\\\ah\\\sq}
\end{document}
