How is it possible to use a costfunction/ penalty function for a Support Vector Machine in the classification Learner App?
If it is not possible, is there a way to train a SVM manually for more than 2 classes?

Hi,
a cost function is not available as far as i know. For more than two classes you could use the function

Hi,
when you choose the option "generate code" from the button export model in the classification learner app you get a good commented script with matlab-code doing exactly what you choosed in classification learner app. Then you can modify for your purposes as you want. If you do SVM model with more than 2 classes, i guess the function classification learner will use
