多个光伏电池组合，可模拟光伏电池并网组合(Combination of multiple photovoltaic cells, photovoltaic cells can be simulated and network combination)

模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。 (Simulated annealing algorithm derived from solid annealing principle, the solid is heated to a sufficiently high, let it cool slowly, when heated, solid particles with temperature becomes disordered state, the internal energy increases, while slowly cooling the particles gradually increasingly ordered at each temperature to reach equilibrium, and finally reach the ground state at normal temperature, which can be reduced to a minimum.)

Hidden Markov Model (HMM) Toolbox written by Kevin Murphy A problem of fundamental interest is characterizing such real-world signals in terms of signal models. HMM is referred to as Markov sources or probabilistic functions of Markov chains in the communications literature.

在MATLAB中实现动画效果 摘要: MATLAB是 MathWorks公司开发的新一代的科学与工程计算软件, 已经成为全球应用最广泛最流行的软件之一。随着该软 件应用的不断普及, 用户对其动画功能的需求也在不断增加。该文主要介绍了在 MATLAB 中实现程序动画、 Flash 动画和影片动画等效 果的方法。具有较强的针对性、 代表性和实用性。(To achieve animation effects in the summary of MATLAB: MATLAB is a MathWorks has developed a new generation of scientific and engineering computing software, has become the world' s most widely used one of the most popular software. With the growing popularity of the software applications, user demand for its animation capabilities are constantly increasing. This paper introduces the program is implemented in MATLAB animation, Flash animation and video animation and other effects of the method. Highly targeted, representative and practical.)

非线性回归,某三次多项式，多元非线性回归分析的例子，很少，很珍贵啊(NONLINER)

1. 按照式计算相似性矩阵 2. 排除自身的相似度 3. 按照式计算归一化矩阵 4. 按照式计算归一化拉普拉斯图矩阵L 5. 计算L的特征向量，将前个特征值最大的向量按列放置成一个矩阵，即依次为前个特征值最大的特征向量 6. 归一化X形成矩阵Y 7. 对矩阵Y按每行为一个数据点，进行k-means聚类，第行所属的类就是原来所属的类。(1. similarity matrix based on formula computation 2. rule out your own similarity. 3. normalized matrix based on formula computation 4. normalized formula Laplasse matrix L according to formula. 5. Calculate the eigenvectors of L. Place the vectors with the largest eigenvalues in columns into a matrix, that is, the eigenvectors with the largest eigenvalues in turn. 6. normalized X formation matrix Y 7. K-means clustering is applied to matrix Y according to one data point per behavior. The first row belongs to the original class.)
