Class Documentation

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

Improved Euler (Heun’s method) integrator.

Second-order explicit method. Better than basic Euler.

Order: 2 Stability: Better than Euler, but still poor for stiff problems Usage: Simple problems where RK4 is overkill
