%Example: GDA
% Description:
%  This function is implimentation of the Generalized Discriminant
%  Analysis (GDA) [Baudat01]. The GDA is kernelized version of
%  the Linear Discriminant Analysis (LDA). It produce the kernel data
%  projection which increases class separability of the projected 
%  training data.
