problem for obtain future data in a closeloop Narx

Sorry for taking so long is that I lie a little mathworks page. Many thanks for your reply Benji Bowbow. i have one last question. I train the narxnet and simulated the network. After, i close loop and simulate the network again. For iterated the network two times i introduce this previous outputs in close loop and simulate again. I am going to explain with code.

%import data%

xlsread p xlsread t

p1=p' t1=t'

inputSeries = tonndata(pn,true,false); targetSeries = tonndata(tn,true,false);

% Create a Nonlinear Autoregressive Network with External Input

net = narxnet(inputDelays,feedbackDelays,hiddenLayerSize);

% Prepare the Data for Training and Simulation [inputs,inputStates,layerStates,targets] = preparets(net,inputSeries,{},targetSeries);

% Train the Network [net,tr] = train(net,inputs,targets,inputStates,layerStates);

% Test the Network outputs = net(inputs,inputStates,layerStates); errors = gsubtract(targets,outputs);

okei ,I get up here

% Closed Loop Network netc = closeloop(net); [xc,xic,aic,tc] = preparets(netc,inputSeries,{},targetSeries); yc = netc(xc,xic,aic);

well, now, for re-iterate i must introduce (yc) in function preparets for simulate again close loop?? As would this comand?? [xc,xic,aic,tc] = preparets(netc,yc,{},{});?? because targets now i have not
