How to Multi-step ahead Predict with NARX

Dear all,

I have been going crazy with the NARX prediction! I have got an input of 400 samples and an output of 400 samples, I need to predict the 401st, 402nd, 403th, 404th, 405th, 406th and 407th output. As you can see I have not got the input data for this prediction.

My code has been generated by ntstool and when it says "multi-step ahead prediction" it actually means one step ahead prediction with an input that the network has not trained with. Am I correct?? How can I predict beyond the known inputs? Would I need to adjust the delays?

I would massively appreciate someone's help.

Thank you very much!

I would really appreciate if someone could help, please?
