3D Runge–Kutta (RK4)

3D formulation of the runge–kutta (rk4). A fourth-order explicit scheme for ODE initial-value problems.

This is the 3d variant of the Runge–Kutta (RK4). RK4 evaluates the derivative at four stages per step to achieve fourth-order accuracy, balancing accuracy and cost for non-stiff ODE systems.
