here it is a diff. equation system i want to solve with Matlab.
Since i cannot format equation here, follow this link please:

The response from Ross_Tang on the thread that you provided would be my approach. (every n order linear ode can be reduced to a set of n 1st order linear ode equations)

Next, I would try to use these solvers in MATLAB:

The behavior of matrix C would be my interest.

Thanks,
