computes the gravitational acceleration vector at a specified ％ ECF location using the JGM2 gravitational ellipsoid only. ％ Higher-order gravity terms (the "gravity anomaly") are ％ ingnored. Only the pure ellipsoid is used. (computes the gravitational acceleration vector at a specified ECF location using the JGM2 gravitational ellipsoid only.

字母图像识别算法，O, E, A, U 四个字母进行识别，该算法加入一定噪声之后依然有效。(The basic goal of the program is to perform letter recognition of vowels O, E, A, U in paragraphs provided in form of black-and-white images. Using the training paragraph image, we are allowed to train our program to distinguish among letters. Some difficulties that need to be resolved are noise, joined letters, scaled or tilted letters, and distinguishing between letters that are similar to each other. )

本程序模拟一个机器人躲避障碍的仿真.其中有不完善的地方 迫于精力有限,具体过程还有点粗糙,读者可以加以修正 (a simulation of the robot avoid obstacles to the simulation. Which forced the inadequacies in the energy are limited, There is a process in concrete rough, and readers can be amended)

对k近邻方法进行改进，knn方法中自动获取k值(Automatic selection of K value in KNN algorithm)

自己写的matlab写的细化程序，特别针对条形的图形(Matlab write their detailed written procedures, especially for bar graph)

Hurst指数是描述非函数长周期的重要指标。它有别于传统单位根检验，可以发现时间序列存在的超长周期性，可以用于判断市场风险，但运算相当繁琐，单独利用Excel计算费时又费力，作者在充分理解Hurst指数内涵和应用的基础上，利用Excel的宏语言VBA编写宏程序轻松实现Hurst指数的计算，通过这一工作也希望能使Hurst指数能够得到广泛的应用。(Hurst index is to describe the function of the long period of non-important indicator. It is different from the traditional unit root tests, time series can be found in the presence of the long periodicity, can be used to determine market risk, but the operation rather cumbersome, separate consuming and laborious calculations in Excel, the authors fully understand the meaning and application of the Hurst exponent based on the use of Excel macros written in VBA macro language easily Hurst index calculation, also hopes to make this work through the Hurst exponent can be widely used.)
