The integrate function expects as parameters the rhs of the ode as defined above, the initial state x, the start-and end-time of the integration as well as the initial time step. Note, that [funcref boost::numeric::odeint::integrate integrate] uses an adaptive stepsize during the integration steps so the time points will not be equally spaced. The integration returns the number of steps that were applied.

It is, of course, also possible to implement the ode system as a class. The rhs must then be implemented as a functor having defined the ()-operator:
