内联列向量显得太大

Question

当我在文本中使用矢量时，矢量显得太大 - 我怎样才能使它变小？

例子：

\documentclass[12pt]{scrartcl}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
One standard basis vectors of $\mathbb{R}^2$ is \begin{pmatrix}1\\0\end{pmatrix}$.
 Unfortunately, the vector is about twice as tall as the rest of the line. 
How can I reduce its size to about $1.5$-times the size of the line?
\end{document}

Answer 1

只需使用psmallmatrixfrom mathtools。

\documentclass[12pt]{scrartcl}

\usepackage{amssymb}
\usepackage{amsmath}

\usepackage{mathtools}

\begin{document}
    One standard basis vectors of $\mathbb{R}^2$ is $\begin{psmallmatrix}1\\0\end{psmallmatrix}$.
    Unfortunately, the vector is about twice as tall as the rest of the line. 
    How can I reduce its size to about $1.5$-times the size of the line?
\end{document}

Answer 2

您可以使用psmallmatrix来自的环境mathtools，或\medmath来自的命令nccmath（约 80% \displaystyle），或者在 footnotesize 中创建一个组。只需选择：

\documentclass[12pt]{scrartcl}
\usepackage{mathtools, nccmath}
\usepackage{amssymb}

\begin{document} 

One standard basis vectors of $\mathbb{R}^2$ is $\begin{pmatrix}1\\0\end{pmatrix}$.
 Unfortunately, the vector is about twice as tall as the rest of the line.
How can I reduce its size to about $1.5$-times the size of the line?

One standard basis vectors of $\mathbb{R}^2$ is $\begin{psmallmatrix}1\\0\end{psmallmatrix}$.
 Unfortunately, the vector is about twice as tall as the rest of the line.
How can I reduce its size to about $1.5$-times the size of the line?


One standard basis vectors of $\mathbb{R}^2$ is $\medmath{\begin{pmatrix}1\\0\end{pmatrix}}$.

One standard basis vectors of $\mathbb{R}^2$ is {\scriptsize$\begin{pmatrix}1\\0\end{pmatrix}$}.
 Unfortunately, the vector is about twice as tall as the rest of the line.
How can I reduce its size to about $1.5$-times the size of the line?

\end{document}

Answer 3

尝试smallmatrix：

\documentclass[12pt]{scrartcl}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
One standard basis vectors of $\mathbb{R}^2$ is $\left(\begin{smallmatrix}1\\0\end{smallmatrix}\right)$.
 Unfortunately, the vector is about twice as tall as the rest of the line.
How can I reduce its size to about $1.5$-times the size of the line?
\end{document}

Answer 4

我只需使用命令\tbinom{1}{0}即可第18页本指南：

我认为这可能是一个不错的折衷方案，它是一个简单的基本命令，而且不是太大。见下图：

\documentclass[12pt]{scrartcl}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
One standard basis vectors of $\mathbb{R}^2$ is $\tbinom{1}{0}$.
 Unfortunately, the vector is about twice as tall as the rest of the line. 
How can I reduce its size to about $1.5$-times the size of the line?
