### 介绍
|
|
|
|
|
|
|
|
|
|
|
|
[LaTeX](https://www.latex-project.org/) 基于 TEX 的排版系统，适用于生成高印刷质量的科技和数学、物理文档。
|
|
|
|
|
|
|
|
|
|
|
|
- [LaTeX 官网](https://www.latex-project.org/) _(latex-project.org)_
|
|
|
|
|
|
- [KaTeX 官网](https://katex.org/) _(katex.org)_
|
|
|
|
|
|
|
|
|
|
|
|
而 [KaTeX](https://katex.org/) 只处理 LaTeX 的数学符号的一个更小的子集，用于 web 上展示
|
|
|
|
|
|
|
|
|
|
|
|
### 示例
|
|
|
|
|
|
|
|
|
|
|
|
```KaTeX
|
|
|
|
|
|
% \f is defined as #1f(#2) using the macro
|
|
|
|
|
|
f\relax(x) = \int_{-\infty}^\infty
|
|
|
|
|
|
f\hat\xi\,e^{2 \pi i \xi x}
|
