代碼：

% 
x = [-0.9, 0.81]; [y, L, B] = QCoeff(x, 3) % Unquantized parameters
r = 0.9; theta = pi/3; a1 = -2*r*cos(theta); a2 = r*r;
p1 = r*exp(j*theta); p2 = p1';% Quantized parameters: N = 3;
[ahat, L, B] = QCoeff([a1, a2], 3); rhat = sqrt(ahat(2));
thetahat = acos(-ahat(1)/(2*rhat)); p1hat = rhat*exp(j*thetahat); p2 = p1';% Changes in pole locations
Dp1 = abs(p1 - p1hat)
Dp1 = 0.0344 

　　運行結果：
