Answer 1

您可以使用siunitx的S[<opt>]列规范来执行舍入。为了简化代码，我定义了一个新的BMATRIX环境来处理每个用例的具体情况（也是为了保持一致性）。

\documentclass{article}

\usepackage{amsmath,siunitx}

\newenvironment{BMATRIX}
  {\left[\hspace{-\arraycolsep}\begin{array}{
    *{\value{MaxMatrixCols}}
    {S[round-precision = 3, round-mode = places]} 
    }}
  {\end{array}\hspace{-\arraycolsep}\right]}

您可以将 调整round-precision为较小的值，然后尝试使用round-mode = figures。S类型列还可确保正确对齐。

Answer 2

一个关键是使用\\[18pt]而不是es&之间bmatrix。此外，我使用&before 和 after eachbmatrix来给每行 3 列...在第 1 列我放置了开始括号，在第 3 列我放置了结束括号。所有包含的bmatrixes 都放在第 2 列。

当然，我也做了\tiny调整。最好是截断每个单元格的数据。
