%NNPLSPRD Predictions using collapsed NNPLS model
%  This program uses the collapsed NNPLS model to predict the responses
%  of a new x block. The inputs are the the input to hidden layer weights 
%  (W12), hidden layer to output weigts (W23), hidden layer biases (B2), 
%  output bias (B3) and new x-block (x). The output is the new y-block
%  predictions (ynpred).
