Compare two equal character vectors. s1 = 'Yes'; s2 = 'Yes'; tf = strcmp(s1,s2) tf = logical 1 strcmp returns 1 because s1 and s2 are equal. Find Text in Cell Array Find the word 'upon' in a cell array of character vectors. s1 = 'upon'; s2 = {'Once','upon'; 'a...
% isqual函数 元胞数组不可以使用 '==' 判断是否相等,可以考虑isqual函数 c = {65,65}; d = {'A',65}; isequal(c,d) 当元胞数组大小相等,对应位置元素等效时返回逻辑值1 字符向量元胞数组: 函数功能 cellstr 其他类型文本转换为字符向量元胞数组 isletter 判断字符是否为字母(或汉字) isspace 判断...
The lengths of that dimension are equal for all arrays. For one or more arrays, the length of that dimension is equal to 1. For the other arrays, the lengths are not equal to 1 but are equal to each other. Character vectors are always compatible with all other input arguments. You can...
nargout简介：在matlab中定义一个函数时， 在函数体内部， nargout指出了输出参数的个数。特别是在利用了可变参数列表的函数中， 用nargout获取输出参数个数很方便。用法：n = nargout n= nargout(fun)2、varargin与nargin的区别 varargin简介：varargin可以看做“Variable length input argument list”的缩写。在mat...
NaN 1]) % NaNs compare as not equal, so this returns c = [1 3] Class support for inputs A and B, where A and B must be of the same class unless stated otherwise: - logical, char, all numeric classes (may combine with double arrays) - cell arrays of strings (...
Actually, as long as the sum of three values you set equal to 100 (here is 20, 30, 50), it will be ok. The other vector N have the same reason. 10. Read images from disks and save these frames into avi video files. 1 %% change the frame to videos to save. 2 clc; close...
