Class Documentation

template<system_state S>
class RK4Integrator : public diffeq::core::AbstractIntegrator<S>

Classical 4th-order Runge-Kutta integrator.

The most famous and widely used fixed-step ODE solver. Excellent balance between accuracy and computational cost.

Order: 4 Stability: Good for non-stiff problems Usage: General-purpose ODE integration
