：MATLAB 是目前在国际上被广泛接受和使用的科学与工程计算软件。虽 然 Cleve Moler教授开发它的初衷是为了更简单、更快捷地解决矩阵运算，但 MATLAB 现 在的发展已经使其成为一种集数值运算、符号运算、数据可视化、图形界面设计、程序设 计、仿真等多种功能于一体的集成软件。 (MATLAB is now widely accepted and used in the international science and engineering calculation software. Although However, Professor Cleve Moler its original intention was to develop a simpler, more efficient solution to the matrix operation, but now MATLAB Has been making in the development of a set of numerical computation, symbolic computation, data visualization, graphical interface design, program design Meter, simulation and other functions in one integrated software)

谱聚类算法建立在谱图理论基础上，与传统的聚类算法相比，它具有能在任意形状的样本空间上聚类且收敛于全局最优解的优点。 该算法首先根据给定的样本数据集定义一个描述成对数据点相似度的亲合矩阵,并且计算矩阵的特征值和特征向量 ， 然后选择合适 的特征向量聚类不同的数据点。谱聚类算法最初用于计算机视觉 、VLS I 设计等领域， 最近才开始用于机器学习中，并迅速成为国际上机器学习领域的研究热点。(Spectral clustering algorithm based on the reproduction diagram theory, compared with the traditional clustering algorithm, it can have on the arbitrary shape of sample space clustering, and the advantage of converge to global optimal solution.The algorithm firstly according to the given sample data set defines a description of the data points of similarity in pairs of affinity matrix, and computing the matrix eigenvalue and characteristic vector, and then choose the appropriate feature vector clustering of different data points.Spectral clustering algorithm was originally used in computer vision, VLS in areas such as design, I recently started used in machine learning, and quickly became a hot issue in the field of international machine learning research.)

说明：  最传统的拓扑优化程序，99行，使用优化准则算法（OC算法）(The most traditional topology optimization program, 99 lines, uses optimization criteria algorithm (OC algorithm))

this file is to solve the problem of the tridiagonal and banded systems

说明：  高斯光束matlab源程序，可以编译修改。(Gaussian beam matlab source, can compile changes.)

模糊K均值算法实现。Fuzzy K Means algorithm.(Fuzzy K Means algorithm.)

The onset of the T wave is the beginning point of the T wave, it s the first negative or null sample preceeding the T peak. The offset of the T wave is the ending point of the T wave, it s the first positive or null sample following the T peak.

说明：  倒立摆的控制，采用常用的PID算法，现在没有加其他的算法，或许对一些同学有用。(Inverted pendulum control, with common PID algorithm, the algorithm is not added to the other, may be useful for some students.)
