Polynomial-Phase-Signal_DOA

说明：  这是CA码的捕获过程仿真，这能帮助我们更好的理解CA的捕获(This is the CA code capture process simulation, which can help us a better understanding of the capture of the CA)

Calculation of Chang E III whereabouts time

度为3的scale free network generating， 速度比较慢，可能是循环次数比较多(Degree scale free network generating 3, the speed is relatively slow, it may be more cycles)

基于L型线阵的信号频率，方位角，俯仰角联合估计，采用MUSIC(Based on the L-linear array of signal frequency, azimuth, pitch angle joint estimation using MUSIC)

4阶龙格库塔方程，给出了一个实例，并且写出详细的步骤和过程，看到就能会。(4-order Runge-Kutta equations, given an instance, and write detailed steps and processes that can be.)

四种聚类算法源代码及示例代码,本程序的最终目的是形成一套标准的用于聚类、可扩展的工具。包括的内容有1. 聚类算法：Kmeans和Kmedoid算法、FCMclust, GKclust, GGclust算法 2. 评估分类原型：程序可以在二维图像上绘制出聚类的结果 3. 验证：程序给每一个算法提供验证机制，每个聚类算法会统计(Partition Coefficient (PC), classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni s Index (XB), Dunn s Index (DI) and Alternative Dunn Index (DII)几种衡量指标。-Four kinds of clustering algorithms source code and sample code, the ultimate goal of this program is to form a set of standards for clustering, scalable tools. Including the contents of a. Clustering algorithm: Kmeans and Kmedoid algorithms, FCMclust, GKclust, GGclust algorithm 2. Assessment classified prototypes: programs can be plotted in two-dimensional image, the results of clustering 3. Verify: Program to provide an algorithm to each authentication mechanism, each clustering algorithm will calculate Partition Coefficient (PC), classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni s Index (XB), Dunn s Index (DI) and Alternative Dunn Index (DII) of several metrics.)
