The origin code author is https://github.com/hxwujinze

Parameters

• formula (str or List[Dict]) – 公式字符串或通过katex解析得到的结构体

• index (int) – 本子树在树上的位置

• forest_begin (int) – 本树在森林中的起始位置

• father_tree (List[Dict]) – 父亲树

• is_str (bool) –

Returns

• tree (List[Dict]) – 重新解析形成的特征树

• todo (finish all types)

Notes

Some functions are not supportd in katex e.g.,

1. tag

   • \begin{equation} \tag{tagName} F=ma \end{equation}

   • \begin{align} \tag{1} y=x+z \end{align}

   • \tag*{hi} x+y^{2x}

2. dddot

   • \frac{ \dddot y }{ x }
