Hybrid Genetic Algorithm PSO Code

包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，进行逐步线性回归，从先验概率中采样，计算权重。( Including the MUSIC algorithm, ESPRIT algorithm ROOT-MUSIC algorithm, Stepwise linear regression, Sampling a priori probability, calculate the weight.)

利用夹角余弦距离进行样本数据分类。实现步骤主要分为以下两部分：a、待测样品X与训练集里每个样品Xi的距离采用夹角余弦距离公式计算。b、循环计算待测样品和训练集中各已知样品之间的距离，找出距离待测样品最近的已知样品，该已知样品的类别就是待测样品的类别。(Using the sample data classification Angle cosine distance.Implementation steps are divided into the following two parts: a, sample under test with each of the samples in the training set X Xi distance using the included Angle cosine distance formula.B, loop calculation under test samples and the distance between the known samples training focus, find out the known closest to the sample under test samples, the samples of known category is the category of the sample under test.)

可有效计算各类熵值，信息熵、样本熵、谱熵计算，与其他程序相似(It can effectively calculate all kinds of entropy, information entropy, sample entropy and spectral entropy, similar to other programs.)

说明：  提取图像的颜色特征，首先将图像颜色映射到指定的8个颜色，然后利用自相关和互相关计算得到图像的特征向量，并从原数据库中算出利用此方法检索图像的正确率，并将检索结果好的图像显示到指定文件夹中。(Extract image s color characteristics.First, the image color map to the specified eight colors, then use the auto-correlation and cross-correlation calculation of image feature vectors.and Calculated from the original database, retrieve the images using this method, the correct rate, and a good image display search results to a specified folder.)

本书介绍了matlab在控制系统中的使用，涉及matlab的基本操作及系统的频谱分析、状态空间分析等内容(This book describes the matlab use in the control system, the content spectrum analysis involves matlab basic operations and systems, state space analysis, etc.)

实现MUSIC谐波分解,对于多个频率的估计(Realize MUSIC harmonic decomposition)

说明：  这是我们学校老师上课时用的课件，其中有一些程序代码(This is our teachers to use the courseware in class, some of which code)
