说明：  图挖掘，图聚类 m文件主要包含4个功能：图的生成，图相似度分析，节点符号化，边权挖掘 ，详细说明见注释(graph mining, graph clustering)

模板匹配法，与梯度和Laplacian算子相比较，除了能增强图像边缘外，还具有平滑噪声的优点。(Template matching method, gradient and Laplacian operator with the comparison, in addition to enhance the image edge, but also has the advantages of smoothing the noise.)

SVG matlab仿真模型 绝好的学习资料 无功补偿 谐波抑制(SVG matlab simulation model excellent learning materials reactive power compensation harmonic suppression)

matlab的pde工具箱很薄弱，同时只能处理有限复杂度的问题，利用comsol强大的有限元分析与多物理场的耦合性，解决相当完美。 matlab与多物理场有限元软件的结合，本程序需要安装matlab7.0以上以及comsol multiphysics 3.0以上版本，建立客户端后可以方便的利用matlab控制有限元软件，进行建模计算。 本程序描述的是点电荷周围的电场以及电势。适合于初学者(The pde matlab toolbox is very weak, and can only handle a limited complexity of the problem, by using comsol powerful finite element analysis and multi-physical field coupling to solve quite perfect. matlab and multi-physics finite element software combination, the above procedure to install matlab7.0 and comsol multiphysics 3.0 or later, after establishing the client can easily control the use of matlab finite element software to model calculations. This procedure describes the electric field around a point charge and the electric potential. Suitable for beginners)

实现参数辨识，可以自己更改当中的某些参数，实现不同对象的参数辨识(To achieve parameter identification, which can change some of their parameters, to achieve parameter identification of different objects)

this function is used for fitting data. This function is used with another function called funct_for_curve_fitting.m and data_for_fitting.txt

说明：  EM最大期望算法：算法是在概率模型中寻找参数最大似然估计或者最大后验估计的算法，其中概率模型依赖于无法观测的隐藏变量。最大期望经常用在机器学习和计算机视觉的数据聚类领域。(EM algorithm)

用matlab编写的用来求解四步相移法的光栅相位的程序(This is a matlab prepared for the four-step phase shift method to solve the grating phase program)

Communition MATLAB (Proakis)书的源程序，很不错(Communition MATLAB (Proakis) source book, very good)

The short term energy function can be computed by splitting the speech signal into frames of N samples
