Difference between Matlab's classify and ClassificationDiscriminant functions.
%% Balanced Classes, easily seperable
data = [randn(2500, 1) ; 1 + randn(2500, 1)];
labels = [zeros(2500, 1) ; ones(2500, 1)];
y_pred = classify(data, data, labels);
TP1 = sum(y_pred == 1 & labels == 1);
temp = ClassificationDiscriminant.fit(data, labels);
y_pred2 = temp.predict(data);
TP2 = sum(y_pred2 == 1 & labels == 1);

The effect of using uniform priors with unbalanced classes.
N1 = 3500; N2 = 1500;
data = [randn(N1, 1) ; 1 + randn(N2, 1)];
labels = [zeros(N1, 1) ; ones(N2, 1)];
for ii = 1:200
cv(ii) = cvpartition(labels, 'Holdout', 0.2);
end
b_pcc = zeros(1, cv.NumTestSets);
for ii = 1:length(cv)
