Latex 中创建矩阵或向量_latex 列向量-优快云博客

本文介绍了如何使用LaTeX的amsmath包创建矩阵，包括矩阵的无括号形式、带方括号、圆括号、单垂直线和双垂直线的形式，并提供了具体的示例代码。

\begin{equation}
  s_{kk'}=
  \left(
  \begin{array}{ccc}
          h_{1k} &
          \cdots &
          h_{nk}
  \end{array}
  \right)
  \left(
  \begin{array}{ccc}
          \bar{q}_{11} & \cdots & \bar{q}_{12}\\
          \vdots & \ddots & \vdots\\
          \bar{q}_{n1} & \cdots & \bar{q}_{n2}
  \end{array}
  \right)
  \left(
  \begin{array}{c}
          h_{1k'} \\
          \vdots \\
          h_{nk'}
 \end{array}
 \right)
\end{equation}

我们可以得到如下效果：

We can create a matrix in LaTeX using the array environment, or simplematrix, matrix, pmatrix, bmatrix, vmatrix, and Vmatrix environments via amsmath package. This article provides some examples on how to create a matrix in LaTeX.

Creating a matrix with array

Here are some examples.

unbracketed matrix

\[
    M =
    \begin{array}{cc}
    x & y \    z & w \    \end{array}
    \]

matrix surrounded by square brackets

\[
    M =
    \left[ {\begin{array}{cc}
    x & y  \    z & w  \    \end{array} } \right]
    \]

matrix surrounded by parentheses

\[
    M =
    \left( {\begin{array}{cc}
    x & y  \    z & w  \    \end{array} } \right)
    \]

matrix surrounded by single vertical lines

\[
    M =
    \left| {\begin{array}{cc}
    x & y  \    z & w  \    \end{array} } \right|
    \]

Using amsmath package

Call \usepackage{amsmath} in the preamble, after \documentclass{}.

The amsmath package environment for matrix:

smallmatrix: inline matrix

$M = \begin{smallmatrix} x&y\\ z&w \end{smallmatrix}$
    $M = \left( \begin{smallmatrix} x&y\\ z&w \end{smallmatrix}\right)$

matrix: unbracketed matrix

$M = \begin{matrix} x&y\\ z&w \end{matrix}$

pmatrix: matrix surrounded by parentheses

$M = \begin{pmatrix} x&y\\ z&w \end{pmatrix}$

bmatrix: matrix surrounded by square brackets

$M = \begin{bmatrix} x&y\\ z&w \end{bmatrix}$

vmatrix: matrix surrounded by single vertical lines
```
$M = \begin{vmatrix} x&y\\ z&w \end{vmatrix}$
```
Vmatrix: matrix surrounded by double vertical lines
```
$M = \begin{Vmatrix} x&y\\ z&w \end{Vmatrix}$
```
