A vector, in programming, is a type of array that is one dimensional. Vectors are a logical element in programming languages that are used for storing a sequence of data elements of the same basic type. Members of a vector are called components. Advertisements The major difference between an...
1. 三者均可以使用下表运算符对元素进行操作,即vector和array都针对下标运算符[]进行了重载 2. 三者在内存的方面都使用连续内存,即在vector和array的底层存储结构均使用数组 不同点: 1. vector属于变长容器,即可以根据数据的插入删除重新构建容器容量;但array和数组属于定长容量。 2. vector和array提供了更好的数...
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。 问...
Test Whether a Vector or Array Consists of Whole NumbersAlain Hauser
I would like to index an N-dimensional array with a vector of length N. In particular, for the 2-dimensional case I am currently doing the following. A = rand(10); v = randi(10,1,2); v = num2cell(v); A(v{:}) However, this approach seems horribly inefficient. Is there not ...

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,...
