color stuff for matlab programming

这个课题设计从地球的近地轨道起飞到达谷神星预定轨道并且着陆在其表面上的一种数值方法。基于有限时间的航行纠正点火而非瞬时推力数值计算和Matlab仿真。最后可以看到空间飞行器从地球的影响球飞到谷神星的影响球的飞行轨迹。(This project explores the mathematical methods and results of designing a mission to land a spacecraft on the asteroid Ceres by beginning in an earth-centered LEO orbit and ending in an orbit prepared to land on the surface of the asteroid. Rather than assume instantaneous velocity changes, course-correcting burns of finite time are considered and analyzed using numerical methods and Matlab computation. The behavior of the spacecraft is observed inside the Earth s sphere of influence, in interplanetary space, and inside Ceres sphere of influence. )

说明：  经验小波变换（EWT）的编写程序，自动划分滤波器组(Wavelet transform (EWT) programming, automatic division of filter)

说明：  matlab 实现dbscan 这是一种基于密度的聚类分析算法，可以发现任意形状的簇，可以发现噪声点。(Realization of DBSCAN with MATLAB This is a density based clustering analysis algorithm, which can find clusters of arbitrary shape and noise points.)

自己编写的一个卡尔曼滤波c++源程序代码，可以借鉴学习(My writing of a kalman filter c++ source code that can be drawn lessons from learning )

多用户检测方向的pastd算法的SIR-迭代次数仿真可以直接运行程序简单明了，MATLAB(SIR-iterations pastd direction of multi-user detection algorithm simulation can run simple programs, MATLAB)

说明：  

说明：  本人收集的古扎拉蒂（Damodar N.Gujarai）《计量经济学基础》（中英文版）书籍及数据，还有《经济计量学精要》是学习计量经济学及金融分析的不二之选，配合matlab中新推出的计量经济学工具箱更是不错的选择(I collect Guzhaladi (Damodar N. Gujarai) &quot basic econometrics&quot (in English) of books and data, and &quot Essentials of Econometrics&quot is the study of econometrics and financial analysis, the best choice , with the new matlab toolbox of econometrics is a good choice)

说明：  通信原理系统仿真系列--ASK的调制。供刚接触到matlab编程的朋友使用。(communications system simulation series-- ASK modulation. For Matlab programming begin to use a friend.)

电机矢量控制模型，控制参数可调，模型可改变成任何电机。(Motor vector control model, adjustable control parameters, the model can be changed to any motor.)
