Class Documentation

template<system_state S>
class RK23Integrator : public diffeq::core::AdaptiveIntegrator<S>

RK23 (Bogacki-Shampine) adaptive integrator.

Second-order method with third-order error estimation. Good for problems that don’t require high accuracy. Lower computational cost than RK45.

Order: 2(3) - 2nd order method with 3rd order error estimation Stages: 4 Adaptive: Yes
