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.

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

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.

It's a standard problem for the ODE solvers, e.g. ODE45, ODE15S etc.
What specific difficulties do you encounter where we can help ?
