11 Feb 2013 Multi Class SVM Model and classify training/test data sets into more than 2 classes with SVM. Author: Cody

If you are getting all 1s, you should try using different options for the svmtrain function. for example:
options = statset('MaxIter',2000000);
models(k) = svmtrain(X_Train,G1vAll,'options',options,...
'kernel_function','rbf','rbf_sigma',16);

Ok, you are not using the function correctly.

load your .mat file, then pass your new variables as parameters to the function.

It sounds like you need to learn how to load .mat files. Simply type 'load xxx.mat' where xxx is the file name. You would then need to sample your data into training, test, and label sets for use with this function.

Can you show the code you are using?

Hello, thanks for your contribution. It helped me out, but it was confusing and I have re-written and uploaded a clearer function that does the same thing. It is only about 15 lines of code. I'll provide a link when it is approved.

24 Nov 2014 Multi Class SVM Model and classify training/test data sets into more than 2 classes with SVM. Author: Cody Amruta

is it GroupTrain vector must be column vector or row vector?
while i am running it for classfication in one program using 'group' as column vector giving me correct answer but for another program it is giving me answer as 1 for all.Then i was tried it for 'group' as row vector it is giving me 6 correct answers out of 10 classes.
Then what to do to get correct classification output?

what is your output?? Everytime it is showing 1.. am i not get which group it is belong?? for example your test set value 3 34 is a group of 2 but it is also showing 1 , why?

Dear All;

I am trying to use this function for more than three classes , it does not work , in the group train , I have { 1,2,3,4}
could you help me
