Can you please tell me how to use multi class classification using support vector machine?

I have studies in material that use fitcecoc, but how to use it. Please dont reply fisheriris example.

Is it like so....

Training_feat = dataTraining(:,1:16);

Testing_feat = dataTesting(:,1:16);

Training_class = dataTraining(:,17);

Testing_class = dataTesting(:,17);

Training=Training_feat;

Group=Training_class;

Sample=Testing_feat;

Mdl = fitcecoc(Training,Group)

Class = predict(Mdl,Sample);

then compare Class with Testing_class?
