科技论文之Latex公式&符号

近期在写文章。有好多数学公式的命令都忘记了。 今天索性一起整理下。


1 能够在文章的作者上引用的符号



2  一些括号使用方法



3 一些高等数学的公式



4  交,并集



5  一些二项式



6 矩阵写法



7  大写和小写



8  异体字母




9 箭头




10  空格




11  一些颜色





附上其它认为不错的一些代码

以上就是我平时大部分都会用到,每一个命令不须要去记, 平时用多了。自然就熟悉了。

 再者, 用的时候 要多多思考,有的时候在公式中用 ||

符号须要直接输入, 可是在文章书写的时候,则要

\left|xxx\right|
   嘿嘿。 还有好多的注意点,大家平时多写写就OK啦~
