遗传算法对一些应用的算例 比较详尽 适合初学者借鉴(Some applications of genetic algorithms more detailed examples drawing for beginners)

目前，MATLAB軟件是只進不出的企業，公司和研究機構，但在更高，從大學生到博士生的學習機構也必須掌握的基本技能是必不可少的計算工具，(At present, the MATLAB software is not only into the businesses, companies and research institutions, but also in institutions of higher learning from college students to doctoral students must master a basic skill is essential computational tools,)

Sky lab calculate position of satellite in GNSS systems and calculate elevation and azimuth them and show them.

说明：  珍藏版，可实现，新K均值聚类算法，分为如下几个步骤： 一、初始化聚类中心 1、根据具体问题，凭经验从样本集中选出C个比较合适的样本作为初始聚类中心。 2、用前C个样本作为初始聚类中心。 3、将全部样本随机地分成C类，计算每类的样本均值，将样本均值作为初始聚类中心。 二、初始聚类 1、按就近原则将样本归入各聚类中心所代表的类中。 2、取一样本，将其归入与其最近的聚类中心的那一类中，重新计算样本均值，更新聚类中心。然后取下一样本，重复操作，直至所有样本归入相应类中。 三、判断聚类是否合理 采用误差平方和准则函数判断聚类是否合理，不合理则修改分类。循环进行判断、修改直至达到算法终止条件。(NewK-means clustering algorithm ，Divided into the following several steps: A, initialize clustering center 1, according to the specific problems, from samples with experience selected C a more appropriate focus the sample as the initial clustering center. 2, with former C a sample as the initial clustering center. 3, will all samples randomly divided into C, calculate the sample mean, each the sample mean as the initial clustering center. Second, initial clustering 1, according to the sample into the nearest principle clustering center represents the class. 2, as this, take the its recent as clustering center of that category, recount the sample mean, update clustering center. And then taking off, as this, repeated operation until all samples into the corresponding class. Three, judge clustering is reasonable Adopt error squares principles function cluster analysis.after clustering whether reasonable, no reasonable criterion revisio)

说明：  集群程序，matlab，分布式计算引擎。startjobmanager,startworker(Cluster program, matlab, distributed computing engine. startjobmanager, startworker)

采用SVM高斯核，对样本进行分类，输入训练集和测试集，输出SVM分类准确率，采用10折交叉验证(This matlab code uses the SVM(support Vector Machine)to classify, and as the same time it uses the cross validation mathod.)

说明：  MATLAB常用函数，包含常用的许多方面的功能，比较适用于初学者。(MATLAB FUNCTION)

说明：  完美的OFDM仿真程序MATLAB 包括所有星座图(Perfect OFDM simulation program MATLAB includes all constellation)
