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 ?

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