I am assuming that you generated a transfer function using idtf command as shown below.

num = [1 4]; 
den = [1 20 5]; 
sys = idtf(num,den); 

The following command can be used to convert idtf data format to tf data format.

[num, den] = tfdata(sys) 

As the output is obtained in cell array format, use num{1} to get the numerator coefficients and use den{1} to get the denominator coefficients.

Refer to the below link for more information.
