Please teach the same Scilab function as MATLAB's feedback function

Dear

Please teach me the same Scilab function as MATLAB’s feedback function.

Specifically, the code of MATLAB and the half-baked code of Scilab are as follows.

MATLAB:
G = tf([.5 1.3],[1 1.2 1.6 0]);
T = feedback(G,1);

Scilab:
s = poly(0, ‘s’);
G = (.5s + 1.3)/(1s^3 + 1.2s^2 + 1.6s + 0)

See feedback - Feedback operation

Dear mottelet

Nice to meet you again from protfor.

I saw
(feedback - Feedback operation)
which you mentioned and solved it.

Thank you very much!
