solve difference equation in matlab

how can i solve following difference equation in matlab?

A(n+1)=(1-i*p)A(n), where p is arbitrary constant and A(0)=A0

The answer obtained by iteration method of the above equation is A(n)=A0*(1-i*p)^(n).

But how we can obtain this answer in matlab?

A quite complicated way by using "ztrans" and "iztrans":
