Dbscan 算法的matlab代码，是经典的聚类算法，可以用来分类(it s Dbscan, a classic algorithm, which can be employed to classify the spatial data. )

能够实现基二的fft的实现，很好用，亲自试用(Base fft implementation, useful, and personally trial)

关于复杂网络中的Betweenness，用matlab计算。(betweenness_centrality(A) returns the betweenness centrality for all vertices in A.)

生物地理算法优化多层感知网络进行特征分类和识别，精度高达97 (Bio geographic algorithm to optimize multi layer perceptron network for feature classification and recognition, the accuracy of up to 97 )

分别是一些MATLAB中有关图象处理的相关命令集(MATLAB were some relating to the relevance of image processing command set)

模拟正弦衍射光栅光强分布，图1中X轴是位置，Y轴是光强，图2，是强度分布(Analog sinusoidal diffraction grating intensity distribution)

利用有限元法，用comsol和matlab软件计算光子晶体三维带隙(With finite element method, using comsol and matlab software to compute three-dimensional photonic crystals band gap )

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.)

根据观测值与状态量，利用卡尔曼滤波算法对未来状态变量进行状态估计(According to the observation and state variables, Calman filter algorithm is used to estimate the state variables in the future.)
