计量经济学中的matlab使用，主要介绍如何使用matlab来解决计量经济学中的问题(Econometrics matlab use, mainly how to use matlab to solve the problems in econometrics)

说明：  正常重力的仿真模型，内含正常重力计算公式，可模拟不同纬度的正常重力(Simulation model of normal gravity, containing normal gravity formula can simulate normal gravity in different latitudes)

matlab写的一个用于显示图形的绘图界面，只需将绘图代码输入，即可单击显示按钮显示图形。(matlab write a graphics interface for displaying graphics, simply enter the drawing code, you can click the Show button to display the graphics.)

贝叶斯分类器实现多类识别，主要用于两类的识别(BAYES_CLASSIFIER function calculates the discriminant functions for two classes. )

两靖rayleigh衰落信道仿真。This m-file uses successive iterations of data to create an animated = effect ％showing the results of passing an unmodulated carrier through a simple = two ％path Rayleigh fading channel. The following formula and diagram ％illustrates the m-file operation. The animation shows, input(blue) ％and the output(red), the the phase shifts, gains, and attenuations ％of the output sine wave or carrier.(Two Jing Rayleigh fading channel simulation.
