说明：  北航数值分析大作业第一题：矩阵的QR分解求特征向量。代码是我在理学院本科期间写的，所有结果已经过Matlab及Mathematica验证，保证算法正确实现。(Numerical analysis of Beihang great job the first question: QR decomposition of matrix eigenvector. Code is written during my undergraduate logical Institute, all results have been verified through Matlab and Mathematica, to ensure it is correct to achieve.)

基于LMS算法的均衡技术在matlab上的仿真应用(Equalization technique based on the LMS algorithm in matlab simulation applications)

另一种思路注入目标进程的方法 可作为拓宽思维的例子(zhuru dll)

基于ATT7027单相多功能仪表代码，可以显示有功，无功功率，电度(ATT7027 electrical digital )

说明：  1.14寸IPS屏stm32硬件SPI，DMA驱动，在KEIL5环境下开发。(unk1 4 inch IPS screen stm32 hardware SPI,DMA drive, developed in a KEIL5 environment.)

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
