cgt = double(testeImagesLabels); clabel = double(Test_predict); cscores = double(Probability);
figure(2) [X,Y,T,AUC,OPTROCPT,SUBY,SUBYNAMES] = perfcurve(cgt,cscores(:,1),1); plot(X,Y,'k');

classNames = net.Layers(end).Classes;
rocSmallNet = rocmetrics(imdsTest.Labels,score,classNames);
p = plot(rocSmallNet,ShowModelOperatingPoint=false)

[predictions,score] = classify(net, imdsTest); % To get prediction score from last layer for each class
classNames = net.Layers(end).Classes;
rocSmallNet = rocmetrics(imdsTest.Labels,score,classNames);
p = plot(rocSmallNet,ShowModelOperatingPoint=false)
