In control systems, we use transfer functions a lot. One way to define transfer function is merely to use tf(). For example, we could define such transfer function as
s=tf('s');
G=(s+1)/(s+3);
But what I would like to do is to define G as G(s) without explicitly defining the underlying transfer function and treat it as transfer function so that I can use Control Toolbox (i.e. feedback(), series(), parallel(),...,etc) to carry out some manipulations. How one can achieve this ?

I realise that. The point is that you can do the symbolic manipulations in the Symbolic Math Toolbox and then manually express the results as Control System Toolbox objects.

Functions like feedback() , series() etc, take in dynamic system models as input arguments. Additional information about dynamic system models can be found here
