Representation of the vector array of Z-transform

% Step 2: Define the Desired Output Vector z with delays ranging N

z = zeros(M+1, 1);

for i = 0:M

z(i+1) = (1)^(-i); % Constructing the z vector with terms corresponding to delays z^{-i}

end

disp('The z vector z:')

disp(z);

Is this code correct for writing this vector array here z represents Z transform terms

Answer 1

Yopu can check it against the Symbolic Math Toolbox iztrans function result —

syms z 
Z = [1 z^-1 z^-2 z^-3].'

t = iztrans(Z)
