hello,
I have a system that is defined in the state space by the command - sys=ss(A,B,C,D);
I am trying to extract the Transfer FunctionTransfer Function from sys by the command G=tfdata(sys).
How can I present the outcome in terms of a division of a numerator and denominator?

display of the result of a tf() would be in multiple lines with a numerator polynomial then dividing line then denominator polynomial .
If you want it all on one line the easiest would probably be to tf2sym from the file exchange . or poly2sym the numerator and denominator and divide.
