i have a transfer function given by
H(z)= 1-z^(-1)/1-z^(-1)+z^(-2)
how to find its impulse response h(n) in matlab what is the code for the same ?

This is how I would do it:
% H(z)= 1-z^(-1)/1-z^(-1)+z^(-2)
b = [1 -1];
a = [1 -1 1];
figure(1)
impz(b,a)

In the same problem what should I do if I want to plot the step response?

Is this a joke? :)
It is -1, -4 0 -2 and zeros to inf.
z^-1 is one sample delay, one step delay
Formarly, use basic knowladge to find H(z) in form H=b/a and then you can use:
h=impz(b,a, length_of_impulse_response)
In your question: b=[1 -4 0 -2] and a=[1 0 0 0]
If it is a joke, then is a good one :)
