我有一张 3 列表,第三列表示一个 $20\times 1$ 向量。我想在这个向量的两边加上方括号。

有人知道如何在向量 P 的两边放置方括号吗?
答案1
您可以通过以下方式实现您的目标:(a) 将环境拆分tabular
为两个array
并排放置的独立环境,(b) 将方括号括起来的列向量放在第二个 中array
,该 仅包含一列。(为什么array
不用tabular
?因为除标题行外,排版的材料都与数学有关;使用array
似乎更自然。)第二个array
环境包含 (i) 标题行和 (ii) 嵌套array
环境,其中包含 20 个元素的向量,用方括号括起来。请注意[0.4pt]
在列向量的每四行后使用额外的间距:这允许 的宽度\hline
,等于(您猜对了)0.4pt
。
我故意将列向量周围的方括号间距设置得比较紧。如果您想要更多空间,可以将该指令替换\begin{array}{@{}c@{}}
为,例如\begin{array}{@{\hspace{1pt}}c@{\hspace{1pt}}}
。
最后,由于我无法访问PhDThesisPSnPDF
文档类,因此我用该类进行了替换article
。
