latex常用符号

博客园公式测试

显示latex格式的公式需要加美元号$，例如 $\beta$ 显示的结果为$\beta$，如果单独一行的公式可用双美元符号，例如$$a+b=c$$会单独成行

\[a+b=c \]

\begin{cases}
x+y=1\\
x-y=1
\end{cases},
\qquad % %后面是接注释，\qquaa表示空格
\begin{aligned}
&\int_{-\infty}^{+\infty}f(x)\mathrm{d}x\\[.5em]
&\sum_{k=0}^n k
\end{aligned}
% &字符号表示对齐，\\另起一行, \\[.5em]里面的.5表示行高

矩阵格式

$\left(\begin{matrix} 1&2&3\\ 4&5&6\\ 7&8&9 \end{matrix}\right) ,\qquad \left| \begin{matrix} a&b\\ c&d \end{matrix}\right| ,\qquad \begin{matrix} a&b\\ c&d \\ e&f \end{matrix}$

\left(\begin{matrix}
1&2&3\\
4&5&6\\
7&8&9
\end{matrix}\right)
,\qquad
\left|
\begin{matrix}
a&b\\
c&d
\end{matrix}\right|
,\qquad
\begin{matrix}
a&b\\
c&d \\
e&f
\end{matrix}

14.间距微调

间距紧凑：\!


$x+y$	`x+y`
$x\!+y$	`x\!+y`
$x\!\!+y$	`x\!\!+y`

间距拉开：\, \; \quad \qquad


$x+y$	`x+y`
$x+\,y$	`x+\,y`
$x+\;y$	`x+\;y`
$x+\quad y$	`x+\quad y`
$x+\qquad y$	`x+\qquad y`
