LaTeX 源文件的每一行称作一条语句(statement),语句可以分三种:命令(command)、数据(data)和注释(comment)。 命令分为两种:普通命令和环境(environment)。普通命令以 \ 起始,大多只有一行;而环境包含一对起始声明和结尾声明,用于多行的场合。命令和环境可以互相嵌套。 数据就是普通内容。注释语句以 % 起始,它在编译...

We can build an array or matrix with the \begin{array} command, and use \left and \right to properly size the delimiters around the matrix: The characteristic polynomial$f(\lambda)$of the$3\times3$matrix \[ \left( \begin{array}{ccc} a & b & c <br />d & e & f <br />g &...
