MATLAB: How i can get state space model from transfer function

Question

Hello, I tried alot with the code you can see in the picture. But it doesn`t work. I want to know if Matlab dosen`t support the function of tf2ss or I just have a mistake.

[code]

num = [0 0 0 5];

den = [1 6 5 0];

[A, B, C, D] = tf2ss(num,den)

[Error message]

Execution of script tf2ss as a function is not supported:

Error in tf2ss (line 6)

[A, B, C, D] = tf2ss(num,den)

Thank you for reading my question and if you know the answer, please leave a comment 🙂

Answer 1

Apparently you named a script ‘tf2ss’. This overshadows the tf2ss function.

The solution is to re-name the script to something that is meaningful and that does not overshadow MATLAB functions.
