表示本身, {}
表示 {}
。當要顯示大號的括號或分隔符時,要用 \left
和 \right
命令。例子:$$f(x,y,z) = 3y^2z \left( 3+\frac{7x+5}{1+y^2} \right)$$
,顯示:
\[f(x,y,z) = 3y^2z \left( 3+\frac{7x+5}{1+y^2} \right)\]git
\left.
或\right.
進行匹配而不顯示自己。例子:$$\left. \frac{ {\rm d}u}{ {\rm d}x} \right| _{x=0}$$
,顯示:
\[\left. \frac{ {\rm d}u}{ {\rm d}x} \right| _{x=0}\]github
$$\frac{\partial^{2}y}{\partial x^{2}}$$
\[\frac{\partial^{2}y}{\partial x^{2}}\]markdown

$\boldsymbol{\hat y} = \boldsymbol{W} \boldsymbol{x}$
$\ell_p$
對於一些特殊的數學符號可使用 \operatorname{}
或者 \text{}
來進行轉換,如:$\text{cov}$
和 $\operatorname{s.t.}$
便顯示爲:\(\text{cov}\) 和 \(\operatorname{s.t.}\)ui
還有:spa
