说明：  卫星导航与定位中的easy程序：将原始观测数据O-files转换到GPS时间（week+sow）；利用原始观测数据N-files中的时间和星历表计算位置的地心地固坐标；从O-files和N-files获得数据，仅使用伪距，对大于20组的数据进行重复计算，并利用迭代最小二乘法，计算接收机地心地固位置等功能。(Easy program in satellite navigation and positioning: convert the original observation data o-files to GPS time (week + sow); use the time in the original observation data n-files and ephemeris to calculate the geocentric and geocentric coordinates of the location; get the data from o-files and n-files, only use pseudo distance, repeat the calculation of more than 20 groups of data, and use iterative least square method to calculate the receiver geocentric and geocentric Fixed position and other functions.)

说明：  利用Fisher线性判别来进行男女分类（里面已经有了男女的数据）(Using Fisher linear discriminant for classification of men and women (which already have the data for men and women))

采用线性滤波法即AR法模拟脉动风速,计算时间短，模拟效果好(Linear filtering AR simulation fluctuating wind speed)

说明：  编写程序：基类base，有一个私有数据成员n，派生类Derived公有继承基类base，Derived中新增加一个数据成员m(Programming: the base class base, there is a private data member n, the derived class Derived inherits the base class public base, Derived add a new data member m)

Least Mean Square algorithm

这是一个关机的小程序，其实作用不大，只不过是做来玩玩的。(This is a small program shut down, in fact, not very useful, just do to play for.)
