mass spring damper transfer function

I've found the equations of motion for a 2dofs system and found the Laplace equtions,which method is used in matlab to find the transfer function from those equations ?

Thanks in advance for help.

[Askic V]

sys = tf(numerator,denominator)

Please have a look at:

yeah this if I already computed the TF, but what i need is finding the TF itself using the established equtions .BTW the equations are long to find transfer function manually .

Please show what you have and we will advise the next course of action.

Thanks everyone, I've found how to implement that using Cramer's rule and using matrices properties in matlab
