sorry ,its a classification task to distinguish between benign and malignant tumor in CT images.

i have 50 images ,so i ran the following code ,which give me 100 % performance in classification at the confusion matrix , my question is are its true or there is something wrong.

load('PZ.mat')
 load('T.mat')
 rng('default')
net = feedforwardnet(9);
net = train(net,PZ,T);
view(net)
%P3 = net (P2);Here i used only 5 charchtristics (contrast  Correlation Energy: Homogeneity entropy):
P3 = net (PZ);
plotconfusion(T,P3)
