I'm trying to figure out how to plot the response of discrete time filters based on their transfer functions. For example, if I have the expression of a filter's transfer function, how do I go about translating that into something I can input into Matlab?
This returns an error due to a zero vector. I understand that the vectors must be nonzero but as you can see from the transfer function, I need two of the coefficients to be zero.
It works! Thanks! When I looked at your post I immediately thought that I would get the same error message about vectors having to be nonzero but ... not this time!
