how should i write followinG transfer function (tf) in the form of nuemrator and denominator in MATAB
-10.45 s^3 - 10.53 s^2 - 0.2246s
-----------------------------------------
s^2 + 1.2116 s - 0.1087 - 0.0909i
following is not working as it returns S^3 in the denominator, but i need s^2 in denominator :
numerator = [-10.45 -10.53 -.2246 0];
denominator = [0 1 1.2116 -.1087 -.0909j];
sys = tf(numerator,denominator);

Ensure no space in .
numerator = [-10.45 -10.53 -.2246 0];
denominator = [0 1 1.2116 -.1087-.0909j];
sys = tf(numerator, denominator)

Or use commas to separate the array elements, then no need to worry about spacing
numerator = [-10.45 , -10.53 , -.2246 0];
denominator = [0 , 1 , 1.2116 , -.1087 - .0909j];
sys = tf(numerator, denominator)
