function [a,b,c,d,e,f,g,h] = trainbpx(i,j,k,l,m,n,o,p,q,r,s,t)
%TRAINBPX Train feed-forward network with fast backpropagation.
%  
%  This function is obselete.
%  Use NNT2FF and TRAIN to update and train your network.

nntobsf('trainbpx','Use NNT2FF and TRAIN to update and train your network.')

%  TRAINBPX can be called with 1, 2, or 3 sets of weights
%  and biases to train up to 3 layer feed-forward networks.
%  
%  [W1,B1,W2,B2,...,TE,TR] = TRAINBPX(W1,B1,F1,W2,B2,F2,...,P,T,TP)
%    Wi - Weight matrix for the ith layer.
%    Bi - Bias vector for the ith layer.
%    Fi - Transfer function (string) for the ith layer.
%    P  - RxQ matrix of input vectors.
%    T  - SxQ matrix of target vectors.
%    TP - Training parameters (optional).
%  Returns new weights and biases and
%    Wi - new weights.
%    Bi - new biases.
%    TE - the actual number of epochs trained.
%    TR - training record: [row of errors]
%  
%  Training parameters are:
%    TP(1) - Epochs between updating display, default = 25.
%    TP(2) - Maximum number of epochs to train, default = 1000.
%    TP(3) - Sum-squared error goal, default = 0.02.
%    TP(4) - Learning rate, 0.01.
%    TP(5) - Learning rate increase, default = 1.05.
%    TP(6) - Learning rate decrease, default = 0.7.
%    TP(7) - Momentum constant, default = 0.9.
%    TP(8) - Maximum error ratio, default = 1.04.
%  Missing parameters and NaN's are replaced with defaults.
