这是显示列矩阵和行矩阵的 MWE。在我看来,两者都很不错,只是第一个有粗垂直线,而第二个有细小的垂直线:
\documentclass[11pt,letterpaper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[total={6in,10in},left=1.5in,top=0.5in,includehead,includefoot]{geometry}
\usepackage{microtype}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{mathtools}
\usepackage{tensor}
\begin{document}
\begin{align}
\Psi &\equiv
\begin{bmatrix}
\phantom{\!\!{}_1} \tensor{\Psi}{_{1}} \\
\phantom{\!\!{}_2} \tensor{\Psi}{_{2}} \\
\phantom{\!\!{}_3} \tensor{\Psi}{_{3}} \\
\phantom{\!\!{}_3} \tensor{\vdots}{_{\phantom{3}}} \\
\phantom{\!\!{}_N} \tensor{\Psi}{_{N}}
\end{bmatrix}\!,
\\[1ex]
\bar{\Psi} &\equiv \bigl[ \: \tensor{\bar{\Psi}}{_1}, \, \tensor{\bar{\Psi}}{_2}, \, \tensor{\bar{\Psi}}{_3}, \, \ldots, \, \tensor{\bar{\Psi}}{_N} \bigr].
\end{align}
\end{document}
以下是预览:
对于第二个矩阵环境(水平矩阵),我尝试了其他矩阵环境,但是很丑,并且没有解决线条粗细问题。
那么我怎样才能使两个矩阵具有相似的垂直线粗细呢?
备用 MWE 代码:

第二个 bmatrix 的垂直线很细,而第一个 bmatrix 的垂直线很粗。如何使它们相同?
