how can I define svd of a transfer function in matlab?

Hi guys. I have a question:

How for G (transfer function) which is SISo (single input -single output) or MIMO(Multi input Multi output) we can define svd in Matlab?

A=[0.5 0 0.025 0;0 -0.01 0 0.017;0 0 -0.025 0;0 0 0 -0.0178];
B=[0;0.035;0.077;0];
C=[0.5 0 1 0];
D=0;
sys=ss(A,B,C,D);
G=tf(sys)
syms s
G =
 
    0.077 s - 0.03754
  ----------------------
  s^2 - 0.475 s - 0.0125
  [U,S,V]=svd(G)
