Example
Edit
5*d3y-4d2y+10y=20*du+4u
The coefficients of your equation are
D=[5 0 -4 10]
N=[20 4]
% Your transfer function
G=tf(N,D)

% There was an error,
5*d3y-4dy+10y=20*du+4u
5 is the coefficient of d3y
0 is the coefficient of d2y
-4 is the coefficient of dy
10 is the coefficient of y
Then
D=[5 0 -4 10]
