How to draw a matrix/array with arrows between rows and between elements?
4 Answers
You may use the tikzmark library to draw around your matrix. Needs to be compiled twice.
\documentclass{article}
\usepackage{amsmath, tikz}
\usetikzlibrary{tikzmark}
\begin{document}
\[
\begin{matrix}
1 & \tikzmarknode{A}{2} & 3 & 4 & \tikzmarknode{C}{5} \\
\tikzmarknode{B}{1} & 2 & 3 & 4 & \tikzmarknode{D}{5} \\
1 & 2 & 3 & 4 & \tikzmarknode{E}{5} \\
1 & 2 & 3 & 4 & \tikzmarknode{F}{5}
\end{matrix}
\]
\begin{tikzpicture}[remember picture, overlay]
\draw[->] (A) -- (B);
\draw[->] (C.-10) to[out=-20, in=20, looseness=2] (D.10);
\draw[->] (C.-10) to[out=-20, in=180, looseness=1.5] ++ (0.5,-0.25) node[right] {$1$};
\draw[->] (D.-10) to[out=-20, in=20, looseness=2] (E.10);
\draw[->] (D.-10) to[out=-20, in=180, looseness=1.5] ++ (0.5,-0.25) node[right] {$1$};
\draw[->] (E.-10) to[out=-20, in=20, looseness=2] (F.10);
\draw[->] (E.-10) to[out=-20, in=180, looseness=1.5] ++ (0.5,-0.25) node[right] {$1$};
\end{tikzpicture}
\end{document}
This is a job for a TikZ CD (the arrow bending is copied from the accepted answer).
You could also customize your arrows using the options of the TikZ library arrows.meta.
\documentclass{article}
\usepackage{amsmath, tikz-cd}
\usetikzlibrary{arrows.meta}
\begin{document}
\[
\begin{tikzcd}[row sep=4pt]
1 & 2\ar[ddl, -{Straight Barb[scale length=3]}] & 3 & 4 & 5\ar[dd,out=-20, in=20, looseness=2, -Triangle]\ar[dr,out=-20, in=180, looseness=1.5, -Triangle]&[8pt] \\
&&&&&1\\
1 & 2 & 3 & 4 & 5\ar[dd,out=-20, in=20, looseness=2, -Triangle]\ar[dr,out=-20, in=180, looseness=1.5, -Triangle] \\
&&&&&2\\
1 & 2 & 3 & 4 & 5\ar[dd,out=-20, in=20, looseness=2, -Triangle]\ar[dr,out=-20, in=180, looseness=1.5, -Triangle] \\
&&&&&1\\
1 & 2 & 3 & 4 & 5
\end{tikzcd}
\]

@LluvioLiu I wouldn't know what your problem is with mathcha but as you can see it works. Mar 16, 2022 at 20:55
It's possible to use {NiceMatrix} of nicematrix and Tikz in the \CodeAfter to draw the arrows.
The arrows are those of the SebGlav's answer.
\documentclass{article}
\usepackage{nicematrix, tikz}
\begin{document}
\[
\begin{NiceMatrix}
1 & 2 & 3 & 4 & 5 \\
1 & 2 & 3 & 4 & 5 \\
1 & 2 & 3 & 4 & 5 \\
1 & 2 & 3 & 4 & 5
\CodeAfter
\begin{tikzpicture}[remember picture, overlay,->]
\draw (1-2) -- (2-1);
\draw (1-5.-10) to[out=-20, in=20, looseness=2] (2-5.10);
\draw (1-5.-10) to[out=-20, in=180, looseness=1.5] ++ (0.5,-0.25) node[right] {$1$};
\draw (2-5.-10) to[out=-20, in=20, looseness=2] (3-5.10);
\draw (2-5.-10) to[out=-20, in=180, looseness=1.5] ++ (0.5,-0.25) node[right] {$1$};
\draw (3-5.-10) to[out=-20, in=20, looseness=2] (4-5.10);
\draw (3-5.-10) to[out=-20, in=180, looseness=1.5] ++ (0.5,-0.25) node[right] {$1$};
\end{tikzpicture}
\end{NiceMatrix}
\]
\end{document}
