演示zeinike多项式拟合的源程序，开发环境为matlabR2006b(Polynomial fitting zeinike demo source, development environment for matlabR2006b)

这是用Gardner算法做的载波同步，其中用到了扩频系统中的PN序列，程序经过仿真，结果正确(Gardner Symbol synchronization )

说明：  用牛顿下山法求解方程：下山因子在计算过程中可以变动，一般选择下山因子时从1开始，逐次将减半进行试算，直到能使下降条件成立为止。若当计算到某步时取不到满足要求的值（或值小到无法容忍），这时称“下山失败”，需要另取初值重新算起。(Descent method with Newton' s equation: down factor in the calculation process can change, usually selected from the 1 start down factor, will be halved for successive spreadsheet until the can down the conditions established. If when calculating the time to take a step not meet the requirements of the value (or values ??too small to tolerate), then the &quot down failed&quot , you need an alternative initial re-counting.)

说明：  使用ID3决策树算法预测销量高低,对数据进行预处理，最终打印并画决策树(Using ID3 Decision Tree to Predict Sales)

power_thermal.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_thermal.rar, Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

经过测试通过的floyd，matlab程序(Tested by the floyd, matlab program)

MATLAB GUI设计学习手记（第二版）源程序 第7章 本书推荐的学习方法： 1）若您是一个MATLAB初学者，且有充裕的时间来学习GUI设计，您可以从本书的第1章开始循序渐进地学习。 2）若您是一位MATLAB初学者，且时间非常紧迫，建议您先学好第1章，然后依次学习第4章、第5章和第6章，其他章节请根据项目需要有选择性地学习。 3）若您已经掌握了MATLAB的基础语法知识，有一定的MATLAB编程基础，也请浏览一下第1章的内容，尤其是专题分析部分。然后先学习本书第4、5和6章，其他章节请根据项目需要有选择性地学习。 4）若您是一位MATLAB GUI方面的专家或老师，您可以将本书作为一本教学的参考书，本书内容全面、讲解详实、代码精炼，是不可多得的GUI宝典。 (MATLAB GUI design learning Hearts (second edition) Chapter 7 book recommended source learning methods: 1) If you are a MATLAB beginners, and there is plenty of time to learn GUI design, you can start from Chapter 1 of the book The step-by-step learning. 2) If you are a MATLAB beginners, and the time is very tight, it is recommended that you first learn to Chapter 1, followed by learning Chapter 4, Chapter 5 and Chapter 6, in other sections based on project needs selective learning . 3) If you have mastered the basic grammar of the MATLAB, the MATLAB Programming Fundamentals, please visit the Chapter 1, in particular thematic analysis section. First learning book chapters 4, 5 and 6, then the other chapters selective learning based on project needs. 4) If you are an expert or teacher of a MATLAB GUI, you can book as a teaching reference books, the book is comprehensive, explain the detailed, refined code, is a rare GUI canon.)

通信系统中的基带信号处理中的成型滤波器代码，已经通过编译。(Communication system baseband signal processing shaping filter code, has passed the compilation.)

水和蒸汽性质计算V5.5，能够计算任何条件下水和蒸汽的参数，能够在matlab下使用。(Water and steam properties calculation V5.5, able to calculate any conditions of water and steam parameters can be used in matlab.)

This is an example of PLL demo
