Newton-Raphson method for all real roots of the polynomial

Advances in data collection and storage capabilities during the past decades have led to an information overload in most sciences. Researchers working in domains as diverse as engineering, astronomy, biology, remote sensing, economics, and consumer transactions, face larger and larger observations and simulations on a daily basis. Such datasets, in contrast with smaller, more traditional datasets that have been studied extensively in the past, present new challenges in data analysis. Traditional statistical methods break down partly because of the increase in the number of observations, but mostly because of the increase in the number of variables associated with each observation. The dimension of the data is the number of variables that are measured on each observation.

Matlab信号处理指导电子书，分数字信号处理工具箱、阵列信号处理工具箱和时频分析工具箱三大部分分别详解且均有实例，全书351page，很不错的matlab信号处理教程。(Matlab Single Processing)

说明：  本程序实现角点检测的功能，有实例可供大家参考。(This program functions for angle detection, there are examples for your reference.)

无功优化的最优潮流程序，可以自行替换ieee数据(Optimal Power Flow)

PD cascade controller for ball and beam

THIS IS SINGLE MACHINE INFINITE BUS SYSTEM

This is not my work but a function I use often. It is much faster than the conv2 function in matlab

说明：  利用MATLAB计算两张图像的信息熵及其互信息.(calculate the entropy of information calculate the mutual information of two information.)

说明：  几点说明： 1、source_main.m为主函数，qpsk.m和spread.m为子函数； 2、在matlab工程目录下运行source_main.m即可； 3、为方便大家理解，特以P-CCPCH信道的处理进行了举例，若大家认为资料有用的话请回帖， 我会将整个WCDMA下行信号源的matlab代码提供给需要的人； 4、为方便初学者学习，特提供了我自己开发时参考的3GPP资料，并在关键位置做了记号。 (Some explanations: 1, source_main.m main function, qpsk.m and spread.m as Functions 2, matlab project directory can be run source_main.m 3, to facilitate us to understand, especially for P-CCPCH channel processing of the example, if we consider the information useful, please Replies, I will put the WCDMA downlink signal source matlab code available to people in need 4, for the convenience of beginners to learn, especially when providing a reference to my own development 3GPP information, and in key positions in the mark.)
