Hi.. Can someone please help me to figure out what is the
problem with the codes below..
Source code:
http://www.mathworks.com/access/helpdesk/help/toolbox/nnet/index.html?/access/helpdesk/help/toolbox/nnet/newnarx.html&http://www.google.com/search?q=newnarx


% A problem consisting of sequences of inputs P and targets T
P = {[0] [1] [1] [0] [-1] [-1] [0] [1] [1] [0] [-1]};
T = {[0] [1] [2] [2] [1] [0] [1] [2] [1] [0] [1]};

% A two-layer feedforward network with a two-delay input and
two-delay feedback is created.
% The network has one hidden layer of five tansig neurons.
net = newnarx(P,T,[0 1],[1 2],5);

% The network is simulated and its output plotted against
the targets.
Y = sim(net,P);
plot(1:11,[T{:}],1:11,[Y{:}],'o')

% The network is trained for 50 epochs. Again the network's
output is plotted.
net = train(net,P,T);
Yf = sim(net,P);
plot(1:11,[T{:}],1:11,[Y{:}],'o',1:11,[Yf{:}],'+')


When I run the program, this error was prompted out:

Error in ==> newnarx at 7
net = newnarx(P,T,[0 1],[1 2],5);
