前推后代潮流计算 把节点按不同类型定义为三类节点，方便计算(Forward offspring flow calculation node according to the different types of definitions for the three types of nodes, to facilitate the calculation)

Algorithm of Netwon and secand method

加权零阶域算法，预测的相对误差大概能控制在5 以内。用于上证指数的预测。(Weighted zero-order domain algorithm to predict the relative error can be controlled within about 5 . For the Shanghai index forecast.)

关于matlab语言与控制系统设计方面的一些例子(Some examples of the the matlab language with control system design)

sobel算子 源代码，能完成图像边缘检测 (sobel operator )

说明：  matlab的信号处理工具箱；内含高阶谱函数，如双谱等，使用很方便(matlab toolbox,hosa,Higher-Order Spectral Analysis Toolbox)

在线向量回归分析，有包涵一个例子和内定函数等(On-line vector regression analysis, there is an example of indulgence and unofficially functions, etc.)

matlab程序很详细,主要是kalman滤波部分程序，轨迹估计，以及误差估计等最小线性误差估计(matlab program in great detail, the main part of the program is the kalman filter, trajectory estimation, and error estimation of the minimum linear error estimation)

本压缩包提供了本人课程教学期间课堂演示的PCM编码与解码、2FSK、2ASK、2PSK调制、基带升弦系统。每个模块达到参数都作了优化，以求获得良好的演示效果，对于学习通信原理课程、本科课程或毕业设计同学非常有用。(The folder include the code for PCM ,2ASK,2PSK,2FSK, base-band raised cosine System. All this was did in the matlab7.0/simulink 。 the parameters in every module prefer in order to get the excellent result .the folder is very useful for students in learning the communication theory and simulink .especially for lesson tasks .)
