WebCompute the Z-transform of exp (m+n). By default, the independent variable is n and the transformation variable is z. syms m n f = exp (m+n); ztrans (f) ans = (z*exp (m))/ (z - exp (1)) Specify the transformation variable as y. If you specify only one variable, that variable is the transformation variable. The independent variable is still n.
