Latex公式用法
其实latex语法都是通用的,无论用在markdown还是哪里,都是一样的.
本文详解了包括字母修饰符,公式数学运算发,希腊字母,方程组和矩阵的格式并给出实例

方程组和矩阵
常用的环境有 matrix,bmatrix,vmatrix,pmatrix,cases,split,其区别为在于外面的括号不同.&用于分隔列，
| 环境 | 效果 | 环境 | 效果 |
|---|---|---|---|
| matrix | 不带括号矩阵 | bmatrix | [12]矩阵 |
| vmatrix | |12|矩阵 |
pmatrix | (12)矩阵 |
| cases | {12 方程组 |
split | &12 &对齐 |
$$ |
\[ \begin{bmatrix} 1&2&\cdots \\ 2&3&\cdots \\ \vdots&\vdots&\ddots \end{bmatrix} \]
$$ |
\[ f(x)=\begin{cases} 1_2&\lim\limits_3&\cdots \\ 2&3&\cdots \\ \vdots&\vdots&\ddots \end{cases} \]
split环境配合&可以把公式对齐
$$ |
\[ \begin{split} \cos 2x & =\cos^2x-\sin^2x \\ 1 & =2\cos^2x-1 \end{split} \]
align环境实现公式自动编号,配合&可以把公式对齐,配合
$$ |
\[ \begin{align} \cos 2x &=\cos^2x-\sin^2x \tag{1.2} \\ 1 &=2\cos^2x-1 \tag{1.3} \end{align} \]
