帮助进一步进行 TeXing

我想在 LaTeX 中重新创建一个图表，所以我尽了最大努力，用矩阵创建了一些东西。我真的很满意，但我仍然没有带有“reële nulpunten”和“complexe nulpunten”的箭头以及下面的两个箭头。有人可以尝试重新创建这些吗？我真的不知道该怎么做……

使用您的修改后的代码（其中包含我下面的原始答案）来回答您的后续问题，您可以在任何您想要的地方添加额外的s，然后根据需要在覆盖\tikzmark{}中注释方程式。tikzpicture

例如：

\usetikzlibrary{tikzmark,calc}

\newcommand{\cfbox}[2]{%
\colorlet{currentcolor}{.}%
{\color{#1}%

注释方程式

原来的

毫无疑问，有更好的方法来管理方程的对齐，但这只是一种使用在顶部绘制注释的方法蒂克兹马克：

\documentclass{article}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{tikzmark,calc}

\newcommand{\cfbox}[2]{%
\colorlet{currentcolor}{.}%
{\color{#1}%
\fbox{\color{currentcolor}#2}}%
}

\definecolor{blauw}{HTML}{0074C8}
\definecolor{bruin}{HTML}{753700}
\definecolor{groen}{HTML}{00E12C}


\begin{document}

\hspace{-50pt}
$ \begin{matrix}
