我尝试过这种方法,但是没有效果,还有其他建议或帮助吗,非常感谢。 这是我的代码:
\documentclass[12pt,letterpaper]{report}
\usepackage[utf8]{inputenc}
\usepackage[OT1]{fontenc}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage[left=2.00cm, right=2.00cm, top=2.00cm, bottom=3.00cm]{geometry}
\usepackage[spanish]{babel}
\begin{document}
\begin{align*}
&M:\hspace{1cm} M^{0} \hspace{1cm}\hspace{1cm} M^{1}\hspace{1cm} \cdots\hspace{1cm} M^{j}\hspace{1cm} \cdots \\
&\downarrow_{f}
&N
\end{align*}
\end{document}
答案1
这可以通过tikz-cd
专用于绘制交换图的包来简单绘制:
\documentclass[12pt,letterpaper]{report}
\usepackage[hmargin=2.00cm,
vmargin={2.00cm,3.00cm}]{geometry}
\usepackage[spanish]{babel}
\usepackage{amsmath}
\usepackage{tikz-cd}
\usetikzlibrary{babel}
\begin{document}
\begin{tikzcd}
M : \dar["f"]
& M^0 \drar["f^0"]
& M^1 \drar["f^1"]
& \dotsm
& M^i \drar["f^i"]
& \dotsm
& \\
N : & N^0 \dots
& N^i
& N^{i+1}
& \dots
& N^{j+1}
& \dots
\end{tikzcd}
\end{document}
