I got the model which is 1/s^2+s+1 I used c2d to make it as discrete domain
y(k)=a1y(k-1)+a2y(k-2)+a3u(k)+a4u(k-1)+a5u(k-2)
%y(k)—the output of the system of k time
%u(k)—the control input of K time
%ai —known constants of System model
X = [x1,x2,x3,x4,x5]'
I try to compute the out put of hidden layer of RBF NN which is
hj = exp(-(( norm(X-cj))^2./bj^(2)));
Please kindly let me know how solve this
Thank you

I do not understand what you are doing.
The obvious model to use is a narxnet with no hidden layers:
net = narxnet(0:2,1:2,[]);
help narxnet
doc narxnet

Hope this helps.
Thank you for formally accepying my answer
