简介:Matlab中解决出现的错误使用 svmtrain (line 234) Y must be a vector or a character array.问题 解决问题 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_matri...
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,...
