The NARX provided by the MATLAB toolbox defines y(t) as a function of past inputs and outputs:
y(t) = f(x(t-1), ... ,x(t-d),y(t-1), ... ,y(t-d))
The standard definition of NARX defines y(t) as a function of past and present inputs and past outputs:
y(t) = f( x(t) ,x(t-1), ... ,x(t-d),y(t-1), ... ,y(t-d))
I have attached a picture to illustrate my question.
What is the MATLAB command to modify the input TDL of my existing NARX model to accomidate the present input?
My illustration shows [0:6], but any help is appreciated to achieve similar results such as [0:5], etc.
