runge kutta方法求解常微分方程(the Runge–Kutta methods (German pronunciation: are an important family of implicit and explicit iterative methods for the approximation of solutions of ordinary differential equations. These techniques were developed around 1900 by the German mathematicians C. Runge and M.W. Kutta.)
