- 支援數學公式
行內公式也是$$...$$,Katex語法和Latex雖稍有差別，但不是很大
評論區也完美支援就很贊?
我只想說PHP可能就是世界上最好的程式語言 - 圖片自動匯入也太牛逼了吧！
下面列出了常用的公式
\begin{aligned}
(\mu(d)\cdot d) \cdot Id(d)
& = \sum_{d|n}(\mu(d)\cdot d)\cdot Id(\frac{n}{d}) \\
& = \sum_{d|n}\mu(d)\\
& = [n=1]
\end{aligned}

\begin{aligned}
V^*(s) &= \max_a \Big( \underbrace{r(s, a) + \gamma V^(s’)}_{=Q^(s, a)} \Big)
\end{aligned}
f(n) = \begin{cases} \dfrac{n}{2}, &\text{if } n \text { is even} \\ 3n+1, &\text{if } n \text{ is odd} \end{cases}
\begin{aligned}
V^*(s) &= \max_a \Big( \underbrace{r(s, a) + \gamma V^(s’)}_{=Q^(s, a)} \Big)
\end{aligned}
