说明：  EM算法作为机器学习的经典算法，本算法为EM源程序，陪带实验(EM algorithm as the classic machine learning algorithms, the source of the EM algorithm, to accompany with the experimental)

如果对通信系统的同步或者频偏感兴趣的话，这将是一个很好的学习代码，我花了很长时间写的(Communication system synchronization or frequency offset of interest, this will be a good learning code, I spent a long time to write)

超材料的参数提取程序，给出了参考的文献。matlab编程，测试可使用(Parameter extraction procedure metamaterials given reference literature. matlab programming, testing can be used)

说明：  matlab 闭曲线B样条的拟合，算例可直接使用，使用时只需要修改nq文件或者aline文件中的u1即可，也可定义u1后直接run aline(matlab closed B-spline curve fitting, numerical example can be used directly, using only a need to amend the nq documents or document aline can u1, u1 can be defined also directly run aline)

50节点的pwoerwrold的示例，可以为从事电力系统潮流计算分析的同学们提供帮助。(power sysetm 50bus in powerwordl)

该算法是lte上行链路的方针，对于初学者有一定的帮助。(The algorithm is LTE Uplink policy, have some help for beginners.)

混沌理论多尺度熵matlab实现函数，内附典型应用文章一篇。(Chaos theory matlab realize multiscale entropy function, enclosing a typical application of the article.)

对整个雷达系统从发射端调制到接收端解调进行仿真，并模拟了雷达系统特有的信道环境(Simulate the whole radar system including moduation at the transmitter end, radar channel, and demoduation at the receiver end.)
