Syntax L = length(X)Description L = length(X) returns the length of the largest array dimension in X. For vectors, the length is simply the number of elements. For arrays with more dimensions, the length is max(size(X)). The length of an empty array is zero. example...
max_words = length(wordsarray)%this is supposed to count the number of words in the array disp (max_words) now, no matter how many words are keyed into the editbox, the only value returned is 1, when it should actually output the number of words in the input string. i know textscan...
L=length(X) 输入数组,指定为标量、向量、矩阵或多维数组。支持复数。 提示 要计算字符串或字符向量中的字符数量,可以使用strlength函数。 length不对表执行运算。要检查表的维度,可以使用height、width或size函数。 说明 L = length(X)返回X中最大数组维度的长度。对于向量,长度仅仅是元素数量。对于具有更多维度的...
Array size, returned as a row vector of nonnegative integers. Each element ofszrepresents the length of the corresponding dimension ofA. If any element ofszis equal to0, thenAis an empty array. IfAis a scalar, thenszis the row vector[1 1]. ...
Length(str) is expressed as the length of the string [the length includes the space bar] 2.矩阵 Matrix 可用A=[1 2 3;4 5 2;3 2 7]举例 Available A=[1 2 3;4 5 2;3 2 7] example B=A’表示矩阵行列将互相变换 B=A’ matrix rows and columns will be transformed into each other ...
x = [7.1, 3.4, 7.2, 28/4, 3.6, 17, 9.4, 8.9]; length(x) % length of x vector y = rand(3, 4, 5, 2); ndims(y) % no of dimensions in array y s = ['Zara', 'Nuha', 'Shamim', 'Riz', 'Shadab']; numel(s) % no of elements in s ...
三、数组(array) 四、数组运算: 五、帮助文档 六、绘图 七、数据导入 八、关系运算 九、函数 (初学时的笔记,比较简陋。后续再整理更详细全面的笔记,) 一、命令行窗口控制语句: 1、save filename: 命令将工作区中的变量保存到称为MAT 文件的 MATLAB 特定格式文件中。
