Solve ODE in matrix form?

[JBlackhole]

To all,

I am looking for a way of writing an ODE in matrix form and solve it (in a matrix form). I am using a 2- dofs system, please see attached.

Can the ODE be solved as it written? I can find plenty of info/tutorials, etc on ODE but never with the matrix notation

Thanks

Regards

Thanks. Was just "playing" around with that and was at the bottom of my "how to do it" list.

At the moment I am trying to learn if the ODE can be solved in the matrix form

look up "state space" in version 15 help.  I think it's what you're after.

Indeed. thanks for the pointer. Never heard (or used!) it. Reading the basic stuff not sure if I can use the matrix notation
