ROC curve using multisvm in matlab?
I used multisvm function in matlab for classification, where I have 100 classes. my problem is the performance of this classifier by using perfcurve. it doesn't give me a correct answer. I wrote this code for perfcurve:
[fpr,tpr]= perfcurve (test_class, results,'true');
I have confused with ('true'), this is for the positive class, but I don't how can I deal with it correctly. thank you in advance.
