For inverting a matrix, Gauss-Jordan elimination is about as efficient as any other method. For solving sets of linear equations, Gauss-Jordan elimination produces both the solution of the equations for one or more right-hand side vectors b, and also the matrix inverse A(-1). However, its principal weaknesses are (i) that it requires all the right-hand sides to be stored and manipulated at the same time, and (ii) that when the inverse matrix is not desired, Gauss-Jordan is three times slower than the best alternative technique for solving a single linear set.

我研究生阶段研究定的方向是网络拥塞管理，而我研究RED算法也有挺长时间了，很久以前就有解析NS中的队列管理算法RED的源代码（red.cc&red.h）的想法，借寒假有时间，匆匆写了一下。有些东西自己也没完全弄懂，但是对于困惑于如何修改RED算法的同学来说，应该有很大的参考价值。 本文档首先分析了RED算法涉及参数的含义，然后给出了主要函数的作用，最后对主要函数的源代码进行了分析。 希望本文档对你有用。 (I set the direction of post-graduate stage of the study is to network congestion management, but I have studied the RED algorithm also has quite a long time, long ago have resolved NS in the RED queue management algorithm source code (red.cc & red.h) the idea, by winter have the time to rush to write a bit. Some things they themselves have no fully understood, but for the confusion on how to modify the RED algorithm for the students, it should be a great reference value. This document first analyzes the RED algorithm is related to the meaning of the parameters, and then gives a major role in the function and finally the main function of the source code analyzed. Hope that this document useful to you.)

VC数字图像处理-图像显示。本实例基于microsoft VC++6.0 SP6 开发环境开发。采用 MFC 架构，多文档视图，可以显示JPG, BMP等格式的图像文件。供初学者参考！

pca分类程序，主要用于脑电信号的分类。具有较好的分类精度！(pca classification procedures, mainly for the classification of EEG signals. Has better classification accuracy!)

windows 驱动备份, 采用c sharp开发.(windows driver backup, using c sharp development.)

将加速度积分成速度位移，并且滤波，很好用(Displacement velocity integral of the acceleration and filtering, the good)

在linux上写程序、做网管的人，或多或少都会几种脚本。脚本语言灵活的变量类型、强大的正则表达式处理能力，再加上linux系统本身的管道、重定向以及丰富的命令行工具，让你编程起来游刃有余-the write procedure, so the network management, will be more or less several scripts. Flexible scripting language variable types, is a powerful regular expression handling capacity, coupled with the Linux system itself pipeline, redirect and rich command-line tool that allows you to cope up programming
