案例解说MATLAB典型控制应用[田敏][程序源代码]，找了很久才找到，希望对初学者有帮助！(Typical control applications MATLAB Case Commentary [Tian Min] [source code], looking for a long time to find, I hope to help beginners!)

拉普拉斯特征映射，采用热核构造权重，是一种基于流行学习的非线性降维技术，可用于图像分割提高聚类的性能(Laplacian Eigenmap is a kind of nonlinear dimensionality reduction technique which based on manifold study, it choose the weights W using the heat kernel and it can be used for image segmentation to promote clustering performance.)

数字信号处理在Matlab V4上的应用，纯英文书，是1997年的老书了，为PWS出版公司出版。与国内的薛年喜版《MATLAB在数字信号处理中的应用》不同，在matlab的入门上介绍不多，需要读者较熟悉matlab。(The Application of Digital Signal Processing in the Matlab V4,published by PWS publishing company in 1997.Compared with the Mr.Xue s version , there is an succinct introductory course in matlab,so that readers should know MATLAB well .)

Multi-phase rectifier based harmonic suppression(The usage of power electronic devices in ship pow er g rids w ill produce a large number of harmonics in the input circuit of converters )

Problem of plane-wave reflection by and transmission through an inhomogeneous dielectric slab. Solution through the finite element solution (FEM) and comparing it with the exact solution and plot the results.

围绕粒子群的当前质心对粒子群重新初始化.这样，每个粒子在随后的迭代中将在新的位置带着粒子在上次搜索中获得的“运动惯性”（wvi）向Pi，Pg的方向前进，从而可以在粒子群的运动过程中获得新的位置，增加求得更优解的机会.随着迭代的继续，经过变异的粒子群又将趋向于同一点，当粒子群收敛到一定程度时又进行下一次变异，如此反复，直到迭代结束.(particle swarm around the center of mass of the current PSO reinitialization. Thus, Each particle in the next iteration will be in the new location with particles in the last search was the "inertia" (wvi ) Pi, Pg orientation, and thus can PSO course of the campaign was a new position, increase seek better solutions opportunities. With the continued iteration, after variation of PSO will tend to the same point. When PSO converge to a certain extent when the next variation, so repeatedly, until the end of iteration.)

This code is used to cut selected part of the image that is of course after you decompress.   And run the code in the image circle separated.
