c = cell(size(A)) creates a cell array the same size as A containing all empty matrices. c = cell(javaobj) converts a Java array or Java object javaobj into a MATLAB cell array. Elements of the resulting cell array will be of the MATLAB type (if any) closest to the Java array ...

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. ...

Thank you so much for the answer. As you can see it is a matrix with multiple rows and one column. What I need to do is to keep the rows with 28 number of chars (most of them starts with 8) and delete the other ones (mostly starting with 5) and then put them into a new mat...
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 ...
解决Matlab遇到的svmtrain (line 234) Y must be a vector or a character array. 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。
so far i can write it to individually work for a numerical array (let B = [ ]) and for a character array (let B = [' ']) however I am unsure how write so it can work for either a character or numerical array. any help would be much appriciated ...
You can store multiple pieces of text in a string array. Each element of the array can contain a string having a different number of characters, without padding. Get str = ["Mercury","Gemini","Apollo";..."Skylab","Skylab B","ISS"] ...
在写关于SVM时,调用svmtrain 函数,出现错误:错误使用 svmtrain (line 234) Y must be a vector or a character array. 出错 main (line 44) cg(i,j) = svmtrain(train_label,Train_matrix,cmd); 解决思路 因为你本身所写的函数,与系统自带的工具箱中的函数冲突了,所以导致机机器本身突然木讷,无法选择,...
