Electric Field Vectors and Equipotential Lines of Quadrupole. matlab code and word and pdf files contained folder.

说明：  matlab的60个小程序，很实用的，主要是解方程(matlab of 60 small programs, it is useful, the main equation is the solution)

介绍了一种可在较短时间内检测到数字电视国标系统工作模式的方法。该方法利用帧头PN序列和PN序列扩展保护部 分的相关特性、循环特性以及0FDM信号部分的周期特性进行判决，可达到很好的检测效果，该方法同时可加入跟踪模块对系统 工作模式的突然改变作出反应。还介绍了两种可以在硬件资源和性能上进行折中的检测方法(Describes a method can be detected in a relatively short period of time to a digital television GB system working mode. The method utilizes the correlation characteristics of the the header PN sequence and the PN sequence extension protective portion, the cycle characteristics of the cycle the characteristics and 0FDM signal portion judgment can achieve good detection results, the method at the same time tracking module may be added to the system working mode sudden change the response. Also describes two hardware resources and performance compromise detection method)

在对比度小的灰度图像中加入噪声，再对图像进行滤波和直方图均衡化，对图像进行增强，并比较了不同参数时的增强效果(In contrast, the gray image by adding a small noise, then the image filtering and histogram equalization of image enhancement, and compared the effect of different parameters of the enhanced)

Distribution System Reconfiguration

张光义院士写的相控阵雷达技术下册部分，是一本不错的参考书(ZHANG Guang-yi wrote academicians phased array radar technology part of the next book is a good reference book)

This program is used to Calculate z transform, s transform..etc

removal of noise by using robust techniques

由图像序列恢复结构:输入至少3帧图像，既可以根据马义的算法求取图像所表针的环境的三维结构(Restore the structure by the image sequence)

matab基础教程，主要运行环境为matlab7.0,是新手入门非常好的指导书籍(matab based tutorial, the main operating environment matlab7.0, is a very good guide book Getting Started)
