PCA Classify Function
Project new samples into PCA model using appropriate scaling.
Xtest = test/second dataset;clsRtest = test/second class. result = PCA model (MVApack) mn = result.mean.X;sd = result.scale.X; X_g1a = Xtest;%X_g2a = Xtrain; X_g2new = (X_g1a-(repmat(mn,[size(X_g1a,1),1])))./(repmat(sd,[size(X_g1a,1),1]));%size(X_g2new) T_g2new = X_g2new*result.P; scores = T_g2new; S = boxplot(X_g2new');
