用FORTRAN实现地理信息功能的插值功能，就是运算速度有点慢-FORTRAN implementation of geographic information with the function of interpolation function, namely, speed of operation is quite slow

GPS精密星历卫星轨道插值运算（采用切比雪夫拟合）matlab程序。直接运行chebshev2.mat文件即可，结果显示在doucument2.mat文件中-Precise GPS satellite orbit ephemeris interpolation operation (using Chebyshev fitting) matlab program. Can run directly chebshev2.mat file, the results are displayed in t

excel和matlab混和编程exlink实现回归与模拟,还有几个插值运算小程序-Excel and matlab mixed programming exlink regression and simulation, there are several interpolation of small programs
