该程序利用4阶龙格库塔方法解二阶常微分方程，该微分方程描述火箭发射时质心运动轨迹。-The program uses the 4th order Runge-Kutta method of second order ordinary differential equations, differential equations describe the mass center when the rocket trajectory.

Runge kutta method of 4th order to solve ODE with shooting technique

To solve the coupled dynamical system, we use the initial condition and the 4th order Runge-Kutta method to find the first 3 values, and so to apply Adams-Moulton method to obtain the approximation solution of the system

这是用四阶龙格库塔法计算半导体激光器速率方程的工程，源代码用C语言书写，开发平台为VC6.0。程序输出数据被写入文件SLdata.txt中，其中第一列为仿真时间，第二列为载流子浓度，第三列为光子密度。为了方便更多相关开发者调试，还提供了一个matlab源文件test.m。test.m用于将计算数据在matlab中用曲线显示。-This is project developed by Visual C++ 6.0 software platform, which uses the 4th orde
