Scanty info.
[ Xc Xci Aci Tc ] = preparets(netc,X,{},T);
[ Yc Xcf Acf ] = net(Xc, Xci, Aci);
where (Xci,Aci) and (Xcf,Acf) are initial and final input and layer states, respectively.
With NARX, you cannot get a valid future output unless you have a valid future input.
If you do not have a valid future input you can try to predict one using NARNET.
Also you could use NARNET to predict the future output!
Obviously, if you do both you can compare and even consider combining.
Hope this helps,
Greg

@Greg Heath hi, I want to ask you about NARX did you have any idea about it ? I’m using NARX to forecasting my datas and calculate the RMSE but the results of RMSE still bad. Plz if you have any idea how to get RMSE lower tell me I really tried everything but I did not find any good results
