LaTeX 备忘清单
|
||
===
|
||
|
||
本备忘单总结了 [LaTeX](https://www.latex-project.org/) 常用显示数学符号的参考列表和一些 [KaTeX](https://katex.org/) 的应用示例。
|
||
|
||
入门
|
||
---
|
||
|
||
### 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}
|
||
\,d\xi
|
||
```
|
||
|

|
||
### 行内展示
|
||
|
||
```markdown
|
||
基于 KaTeX 在一行
|
||
展示示例： `KaTeX:\int_0^\infty x^2 dx`
|
||
```
|
