latex软件 方法/步骤 1 语句如下:\begin{align*}\begin{split}M_{1}= \left \{\begin{array}{ll} M_{ij}(0), & case 1\\ \sum^{N}_{j=1,j\neq i}M_{ij}, & case 2\\...
output
(k2)=k(k−1)2:也可以直接这样打:$$ {\left( \begin{array}{c} k\\ 2\\ \end{array...
\begin{equation} \label{eq} \left\{ \begin{aligned} \pi & = 3.141\cdots \\ \sqrt{2} & =1.414\cdots \end{aligned} \right.\end{equation}
解:这个符号用LATEX打是:(k2)=k(k−1)2LATEX代码是:\\ \left(\begin{eqnarray}k\\2\end{...
- $\left(_{a+b+c}^{a+b}\right)$ - $\binom{a+b+c}{a+b}$ - $\dbinom{a+b+c}{...
- $\left(_{a+b+c}^{a+b}\right)$ - $\binom{a+b+c}{a+b}$ - $\dbinom{a+b+c}{...
可使用 amsmath 宏包,如(k2),命令 $\binom k2$,还有 \dbinom k2,\tbinom k2,效果自测吧....
Emmm,几分钟后自答下,用了aligned就支持了= = \left\{ \begin{aligned} x\\ d \end{aligned} ...
