在移动数据通信系统信号经传播媒介到达接收端会发生畸变，现行的通信系统普遍采用 自适应均衡技术来克服ISI和多普勒扩展。自适应均衡技术需要重复发送已知的训练序列直至 有效均衡为止I。“盲均衡(Blind Equalization，BE)111”技术仅利用接收序列本身的相关性便可 均衡信道特性。(Signal in the mobile data communication systems to reach the receiver via the mass media distortion occurs, the existing communication systems are generally adaptive equalization to overcome ISI and Doppler spread. Adaptive equalization techniques need to send a known training sequence repeated until an effective balance date I. " Blind equalization (Blind Equalization, BE) 111" technology is only used to receive serial correlation in itself can be balanced channel characteristics.)

matlab gui很好的例子，对学习有很大帮助。(matlab gui good example of great help in learning.)

应用启发式算法-粒子群算法PSO，解决物流配送中心选址问题，结果好的解决了上述问题，值得参考。(PSO Particle Swarm algorithm using heuristic algorithm to address the logistics distribution center location problems, resulting in a good solution for this problem, it is also useful.)

As a consequence, more exact models of devices can be retained for analysis rather than the approximate models commonly introduced for the sake of computational simplicity. A computer icon appears in the margin with each introduction of MATLAB analysis.

尝试制作界面菜单（uimenu）和上下文菜单（uicontextmenu、uimenu），兵士菜单项能够实现一定功能； 尝试使用menu函数实现简单功能； 为plot绘制的点型增加其他属性修改功能，如markerfacecolor和markersize等； 尝试实现mesh和surf的属性修改界面； 尽可能实现更多的GUI内容。(Trying to create interface menu (uimenu) and the context menu (uicontextmenu, uimenu), soldiers can achieve certain menu item function Try to use the menu function realization of simple function Plot for drawing the point type added other attributes revise functions, such as markerfacecolor and markersize, etc. Try to realize the mesh and surf attributes revise interface Realize more GUI content as possible. )

特征提取代码，提取pca_sift特征，用于图像特征提取，图像配准或匹配，可供做这方面研究的同学参考。(feature extraction image matching)

对harrris算法进行改进，使得伪特征点减少，以及时间效率更佳(Improve harrris algorithm, making false feature points reduce, and better time efficiency)

This book is for people who want to solve ordinary differential equations (ODEs), both initial value problems (IVPs) and boundary value problems (BVPs) as well as delay differential equations (DDEs). Solving ODEs withMATLAB is a text for a one-semester course for upper-level undergraduates and beginning graduate students in engineering, science, and mathematics. Prerequisites are a first course in the theory of ODEs and a survey course in numerical analysis. Implicit in these prerequisites is some programming experience, preferably in Matlab, and some elementary matrix theory. Solving ODEs withMATLAB is also a reference for professionals in engineering, science, and mathematics. With it they can quickly obtain an understanding of the issues and see example problems solved in detail. They can use the programs supplied with the book as templates.

此为智能技术中ICA的代码，快速IcA的代码(This is smart technology ICA' s code, the code quickly IcA)

离散傅立叶变换已成为数字信号处理的重要工具，然而，它的计算量较大，运算时间长，在某种程度上却限制了它的使用范围。快速算法大大提高了运算速度，在某些应用场合已能作到实时处理，并且开始应用于控制系统。(Discrete Fourier Transform digital signal processing has become an important tool, however, the calculation of its larger, long computing time, but in a way limits the scope of its use. Fast Algorithm for greatly enhanced speed of operation, in some applications has been able to do real-time processing and control system began to be used.)
