Why the transfer function involving exponential term comes out in matrix form? Not in usual polynomial form, in particular Net variable in below code

s=tf('s');
G=7.46*exp(-2.668*s)/( 1+2.562*s);
K=7.446;
T=2.5652;
L=2.668;
Lambda=0.089;
alpha=0.28;
C_=(1+T*s)*(1+alpha*T*s);
C_den=(1+Lambda*T*s)^2*1 ;
F=- (1+alpha*T*s)*exp(-L*s);
Net=C_/(C_den+F);
Its a snippet of How Net variable is visible

"Net" results in an irrational expression and is therefore converted to a state-space model. The above transfer function can be modelled using Pade approximation. A similar query to yours is answered in the link below.
You can find the documentation for Pade approximation and tf” here.
