错误:类型为"double"的输入参数的未定义函数或方法"svmtrain" [英] Error: Undefined function or method 'svmtrain' for input arguments of type 'double'

问题描述

我在跑步

SVMStruct = svmtrain(xTrain, yTrain);

我得到的错误是

Undefined function or method 'svmtrain' for input arguments of type 'double'

我很确定xTrain和yTrain是矩阵:

I am pretty sure xTrain and yTrain are matrices though:

size(xTrain)
ans =
544    28


size(yTrain)
ans =
544     1

知道这是怎么回事吗?

推荐答案

听起来svmtrain函数不在您的路径上.如果

It sounds like the svmtrain function isn't on your path. If

which svmtrain

显示未找到svmtrain"，则应确保具有生物信息学工具箱(键入ver并查看它是否在列表中)并且在

displays "svmtrain not found", then you should make sure that you have the bioinformatics toolbox (type ver and see if it is in the list) and it is in your path.
