matlab 模型保护程序对模型进行保护，编译成obj文件(matlab model protection ,we complier the sfunction .c file to mexw file and .obj file)

欧拉角表示法具有简便、几何意义明显等优点，同时姿态敏感器可以直接测出这些参数，能较方便地求解用这些姿态参数描述的姿态动力学方程。但采用欧拉角的姿态描述方法存在奇点问题，且需多次三角运算。而采用四元数表示方法则可以避免这些问题。(conversion between euler angle and quaternion method)

多次仿真时目标轨迹的MSE,可以得到多次仿真时所有采样点的误差平均值的多个数据(MSE of target trajectory when simulated many times)
