in a differential equation of this type
My'' = y' + y + a
where M is the mass matrix and a is a constant.
Using ODE solver and transforming the diff equation in the cauchy form, How can i get the solution for every step also for the y''?

Hi Giacomo, when you solve the ODE this means you have solutions for y(t) and y'(t). You can then simply use the same equation from your ode function to compute y''.
