Code for Solving following second order matrix differential equation

Could you help me to write matlab code for solving following matrix differential equations?

where

In here, the matrices M,C,K,P are as follows ( M,C,K are nxn matrices and V,P are nx1 matrices)

In here, l,P,A,rho,\alpha,v,N,E,I are constants.

[M]

l,P,A,rho,\alpha,v,N,E,I are constants and with known numeric values or you want to use symbolic computation ?

[student_md]

I want to use numerical computation. We can define them as any real number. The values are not important for me. Just code is important.

[Torsten]

It's a standard problem for the ODE solvers, e.g. ODE45, ODE15S etc.

What specific difficulties do you encounter where we can help ?
