RK4\ Runge-Kutta 4th Order ODE Solver {#rk4-runge-kutta-4th-order-ode-solver align=”center”} ================================


RK4 is a C++ library which implements a simple Runge-Kutta solver for an initial value problem.

The rk4() function does not include any error estimator. It takes a single step at a time, requiring the user to control the step size.
