矩阵化编程的一般思路是利用数学上矩阵运算规则、矩阵的数组运算以及bsxfun函数,必要时辅以矩阵操纵。 字符串,Cell数组,Table,Struct: 字符串,Cell数组,Table,Struct本质上都是数组。字符串的元素是char;Cell数组的元素是cell,cell相当于一个容器,其中可以存任意类型,如double型矩阵,字符串,甚至是cell,cell 的内容用{...

“Matlab”是“MatrixLaboratory” 的缩写,中文“矩阵实验室”,是强大的数学工具。本文侧重于Matlab的编程语言侧面,讲述Matlab的基本语法,以及用Matlab语言进行程序设计。值得一提的是,Matlab从R2014a版本开始支持中文语言了! 1.基本概念 Matlab默认启动后界面: ...
