I am getting error using following code with SVM

SVMStruct1 = svmtrain(data,class,'kernel_function','linear');
class12=svmclassify(SVMStruct1, pdg(:,1:end-1));

Error I get is

??? Error using ==> svmclassify at 53
The first input should be a struct generated by SVMTRAIN.

I dont see a reason why it shouldnt run. Any pointers would be greatly appreciated.

Note: I just tried running the examples from the matlab webpage, but it wont even run. My guess is that somewhere something is corrupt.

Thanks

在 MATLAB Online 中打开

Type

which -all svmtrain

What does it tell you?

Thank you so much. That command definitely helped, i had two definition of that function. But when I did, get to definition it will take me to the one that I wanted to use but not to the one that it was actually using, which made me think I was using the right one. but that wasnt the case.
