Plot Output of Digital Transfer Function, Given Input Transform

Hi,

I would like to plot the frequency response (output) from my transfer function with given input.

Please could you advise which Matlab function to use

Hence, i am after Y(z) from H(z) * X(z)

I have z transformed my inputs to X(z) and I know my transfer function H(z), I just need to plot the response of the system.

If you got a transfer function already, you can use freqresp().
