工程中很多的地方用到龙格库塔求解微分方程的数值解，龙格库塔是很重要的一种方法，尤其是四阶的，精确度相当的高。 -project many places used for Runge - Kutta numerical solution of differential equations. Runge - Kutta is a very important one, especially in four bands, precision is high.

提供龙格库塔积分程序，火箭入轨的判据。有一定的深度。具备相当的参考价值-provide Runge-Kutta calculus, fire arrow-format input . Have certain specific depth equivalent basis references
