I have 7 degrees of freedom model, meaning I have 7 dynamic equations, each of them including terms such as x(double dot), x(dot), phi(dot) and theta(dot). The rest are simply damping and stiffness coefficients. I have organised them in the following;

[m] (x double dot) + [c] (xdot) + [k] (x) = F

I would like to know if it is possible to convert such a system of equations into state space form via MATLAB, since it is too complicated and tedious to do convert it myself since each equation consists of around 35 terms each.

Thanks
