% Main_Program dcm3_nn.m.
% Find a NN to replace the FIS in [P T] described
%   in Example 6.7-1

% Input pattern
P=P';
% Target
T=T';N=length(T);P=P(:,1:N);
% New Feedforward NN
net = newff([-1 1;-1 1],[2 1],{'tansig' 'purelin'});
net.trainParam.epochs = 500;
net.trainParam.goal = 1e-10;
% Training
net = train(net,P,T);
% Get the Neural output
Y = sim(net,P);
% Reprint the Target
T;
% Display weights and bias
W10=net.IW{1,1}
B10=net.b{1}
W20=net.LW{2,1}
B10=net.b{2}
% Plot the target and neural outputs
sample=1:length(T);
