Inverse Z-transform - MATLAB iztrans
www.mathworks.com › help › symbolicCompute the inverse Z-transform of 1/ (a*z). By default, the independent and transformation variables are z and n , respectively. syms z a F = 1/ (a*z); iztrans (F) ans = kroneckerDelta (n - 1, 0)/a Specify the transformation variable as m. If you specify only one variable, that variable is the transformation variable.
Z-transform - MATLAB ztrans
www.mathworks.com › help › symbolicCompute 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.
