以下是这些数据结构及其基本操作的代码示例: 1. 向量 创建和操作向量 % 行向量 rowVector = [1, 2, 3, 4, 5]; % 列向量 colVector = [1; 2; 3; 4; 5]; % 访问元素 firstElement = rowVector(1); % 修改元素 rowVector(2) = 10; % 向量长度 vectorLength = length(rowVector); 1. 2. ...
["123";"ab"] %可行 %% 补充 length(c) %字符向量长度 length(s) %字符串数组长度 strlength(s) %字符串元素的长度 %% 字符串型索引 s=["123","abcd";"自由未知数","%$%#"] s(1,2) %常规组合索引 s{1,2} %索引字符串的元素内容,返回字符向量 s{1,2}(1:2) %索引元素内容后,用二级...
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{...

(2001) present an analytical approach for producing efficient hardware implementations by varying the word length and scaling of each signal in a Simulink block diagram. Hwang et al. (2001) demonstrate a visual design flow that addresses issues including the mapping of system parameters, such as ...
