Thread Subject: svmtrain 'how it work'

hello
 i want to know how can i use SVMtrain and SVMclassify as i have created bag of words "codebook" and create histogram for trained data then i want to use SVMtrain but i don't know how to use as groups refer to ? and data refer also to?
svmStruct = svmtrain(data(train,:),groups(train),'showplot',true);
classes = svmclassify(svmStruct,data(test,:),'showplot',true);


thanks

Take a look at the definitions of the groups input to SVMTRAIN in its
documentation:

http://www.mathworks.com/help/toolbox/bioinfo/ref/svmtrain.html

the definition of the sample input to SVMCLASSIFY in its documentation:

http://www.mathworks.com/help/toolbox/bioinfo/ref/svmclassify.html

and the general documentation on support vector machines.
