I have a 2 dof vibration system, I have determined the differential equation of the model, can I determine the trasfer function readily with matlab, without using manual algebra operation?(adsbygoogle = window.adsbygoogle || []).push({});

In other word, I have that differential equation system:

[m]x''+[c]x'+[k]x=[f]

where:

[m] mass matrix

[c] damping matrix

[k] stiffness matrix

[f] external forces matrix

through laplace transformation I obtain:

s^[m]x(s)+s[c]x(x)+[k]x(s)=[f]

where s is the laplace variable, how can I find [f]/[x]?

I'm searching a way for estimating readily the transfer function of mechanical system, it is a loss of time to perform the calculation every time
