MUSIC算法是基于天线阵列协方差矩阵的特征分解类DOA估计算法，这里给出的是基于四阶累计量的MUSIC算法。(MUSIC algorithm for DOA estimation algorithm is based on the decomposition characteristics of the antenna array covariance matrix given here is based on the fourth-order cumulant MUSIC algorithm.)

对啁啾和色散概念的理解，通过MATLAB编程实现可视化(matlab code for chirp and dispersion)

利用matlab进行时频分析的程序，傅里叶变换、短时傅里叶变换、小波分析等等，功能十分齐全。(Using matlab to process time-frequency analysis, Fourier transform, short time Fourier transform, wavelet analysis, etc., function is complete.)

1. 图像二值化 2. 边界跟踪，去除离散点 3. 边界提取 4. 删除短边 5. 区分河流与道路 先找到桥梁，利用桥梁上的种子点 对道路进行跟踪，从而提取整条主干道。 (1 image binarization 2boundary tracking, removal of discrete points 3 boundary extraction 4 Remove the short side 5 distinguish rivers and roads the curvature is too large) First find the bridge, the bridge on the use of seed points on the road to follow, thereby extracting the whole trunk.)

说明：  都市供求信息网分为前、后台两部分设计，前台主要实现信息的显示、搜索与发布功能，其中信息的显示包括列表显示与详细内容显示，而列表显示，又分为首页信息列表显示、查看某类别下所有信息的列表显示和搜索结果列表显示；搜索功能主要包括定位搜索和模糊搜索。后台主要实现的功能为信息显示、信息审核、信息删除、付费设置与退出登录，其中的信息显示功能也分为列表显示与详细内容显示。(Supply and demand information network before the city divided into two parts design background, foreground main achievement of the display, search and publishing of information, which displays information including a list of displays and display details, but the list is displayed, the information is divided into the Home display list, see Under a category displays a list of all the information and the search results list displays Search functions include positioning search and fuzzy search. The main function of the background information display, information auditing, information deleted, pay setting and exit the registry, which is also divided into the information display function displays detailed contents list display.)

几种变化检测算法的简单演示，包括比值法，归一化法，相关系数法三种方法(Several simple demonstration of the change detection algorithm, including ratio method, normalization method, three methods of correlation coefficient)

可变次数的 曲线拟合 最小二乘算法实现 (Variable number of least squares curve fitting algorithm)

rsqp算法的工具包，很有用很好呀，希望有用(pso)

考虑典型的盲信源分离问题，用自然梯度算法实现盲信号分离。在盲信号分离中，用串音误差：作为衡量信号分离的性能指标。 (Consider the typical problem of blind source separation, natural gradient algorithm using blind signal separation. In the blind signal separation, with the crosstalk error: signal separation as a measure of the performance indicators.)

信号包络提取代码。可以方便地获取信号包络曲线。应用效果较好！(envelope matlab code)
