通过修改参数，可以生成各类情况下卫星与陨石的坠落轨迹-By modifying the parameters, we can generate all kinds of cases of the satellite and the impact of the fall trajectory

个人所写matlab代码，应用三维坐标变换原理在空间中模拟行星运动轨迹。其中涉及3维作图，图形object，矩阵变换等等。-Written by myself, the use of three-dimensional coordinate transformation principle in space simulation of the planet s trajectory. Which involves three-dimensional mapping, graphics objec
