Since your model is not nonlinear, just use NARXNET with no hidden nodes.
X = con2seq(giveninput);
T = con2seq(giventarget);
net = narx(1:2,1:2,[]);
The rest follows from the documentation examples
help narxnet
doc narxet
Hope this helps

Not exactly sure what you mean by "the" coefficients. The net is a nonlinear transformation. The coefficients corresponding to the inputs of the hidden node neurons are given by the input weight matrix IW = net.IW.
Hope this helps.
