[X,Y,T,AUC2,OPTROCPT] = perfcurve(classtest,classpredict,2);
My classtest as well as classpredict are 460*1, but when i run perfcurve i get x 3*1 and so it y.
I do not understand why is it so. As X,Y are used to draw ROC, I think it should give both of them as 460*1. I must be missing something.
Thank you for your time.

Could it be that you have relatively few distinct values of classpredict?
