1.创建结构变量,使用struct函数,此处假设电脑超市存储他们的销售信息,包括item_no,cost,customer, code等,因此,每一个结构变量都有四个域,必须使用域名访问其中存储的值 package =struct('item_no',123,'cost',19.99,'price',39.95,'code','g') 结果:package=structwith fields
Matlab中用于创建结构体的函数为struct()。 The structure type is not defined by the system, but needs to be defined by the software users themselves. The function used to create structures in Matlab is struct(). 3.1 struct(field, value) 此函数用于创建具有指定字段和值的结构体数组,value部分输入...

二是使用struct函数构建: 二者使用上,个人倾向于第二种,对这种比较熟。 3.2 访问结构对象 直接赋值访问就行: 4. 单元数组 单元数组是一种广义矩阵。与C语言的数组不同的是,MATLAB中的单元数组的每一个单元都可以是一个数组。以下分别从创建,访问来简单的介绍单元数组。
