% Program 3_12
% Power Series Expansion of a Rational z-Transform

% Read in the number of inverse z-transform coefficients
% to be computed

% Read in the numerator and denominator coefficients of
% the z-transform
num = input('Type in the numerator coefficients = ');

% Compute the desired number of inverse transform
% coefficients
