How do I determine transfer function from input/output data?

I have a discrete-time data set with the following values: u(k)=0 for all k except k=1. When k=1, u(k)=1 (I am basically supplying an impulse signal at one specific time value) y(k)=0 for all k except k=1,2,3. When k=1,2,3 y(k)=1
I need to determine a discrete-time transfer function from this data, and generate a plot of this information. Any pointers would be greatly appreciated.

Why do you need Matlab for this? The transfer function is basically, h(k) = 1 for k = {0, 1, 2} and 0 everywhere else.

If it was filter sort of thing the TF would be available as a X(k+1) = A x(k) + B u(k) form. This would make sense to derive in the Z domain. What you have is what we call as a pulser. If my input changes from 0 -> 1 I send out a pulse for 3 frames.
