MATLAB Online에서 열기 Ran in: It's kind of hard to tell what exactly you want, since your example isn't really proper syntax. If you just have a scalar cell array with a char vector: A = {'potato'}; B = A{:}
在使用MATLAB进行SVM分类器训练时,有时会出现以下错误提示:svmtrain (line 234) Y must be a vector or a character array. 这个错误是由于目标变量Y的类型不正确导致的。本文将介绍如何解决这个问题并提供具体的示例代码。 问题分析 错误提示中明确指出,错误发生在svmtrain函数的第234行,错误的原因是Y必须是一个...
Convert character array to string in MATLAB Matlab提取特征值是经常要读取多个图片文件,把文件名保存在数组中后再读取会出错。从stackoverflow中找到如下解决方法: I've a M by N matrix, each cell contains a character array, that is an image path. How can I use it to read image? It should be ...
Matlab抛出的异常说明str2num函数使用错误,参数必须是字符数组(char array)或者是字符串(string)。在后台看了下获得的listbox里面的数据如下: list_string = ' 56 30 3.09 0' ' 32 46 3.83 30' ' 19 48 3.91 76' ……(省略一大堆数据) ' 31 301 9.79 6634' ...

TF =1x5 logical array1 0 0 1 0 You can sum overTFto find the number of matches. num = sum(TF) num = 2 UseTFas logical indices to return the matches inC. If you index using smooth parentheses, then the output is a cell array containing only the matches. ...
Open in MATLAB Online I have converted a string array to a character array ThemeCopy c = cellstr(bb) d = char(c) when i index variable d, it gives me vertical characters instead of horizontal. for example i have a character string 'ATG' and another 'GCB'. d(2) should give me '...
