说明：  用LMS算法实现自适应均衡器的MATLAB程序(LMS algorithm with adaptive equalizer for MATLAB program)

this program simulate the motion of harmonic oscillator

产生速率160Gbit/s,脉宽1.25ps的一阶高斯脉冲模拟序列（101101）(Production rate of 160 Gbit/s, pulse width 1.25ps first order Gaussian pulse simulation sequence (101101))

一个对数据处理的Matlab函数，统计数据的概率分布并画出概率密度曲线，已经验证，将该函数安装在函数工具箱内即可调用。(A data processing of Matlab function, the probability distribution of the statistical data and draw the probability density curve, have tested, the function will be installed in the tool can function call. )

哈哈镜各种变形原代码，读入待制作的图片，实现图片的缩小放大、水平外凹、水平外凸、梯形变形、三角形，S形和波浪型。(DistortionLi various deformation original code to be read into the production of pictures, the pictures achieve narrow enlarge level Au, Spirogyrate level, trapezoidal deformation, triangle, and the S-wave type.)

matlab程序，解决sift算法对图像特征点的检测，描述和匹配，特征点个数的计算以及程序运行时间，可与其他算法做比较，直接修改参数即可运行(matlab for image matching，include the time and the number of the interest points)

UWB，超宽带信号分析所用的子函数，第一部分！(UWB, ultra-wideband signal Functions used in the analysis, the first part!)

对于大电网潮流计算的一些matlab程序，来源《大电网快速稳定分析关键基础技术研究(Power flow calculation for large number of matlab program, the source of " big power and rapid analysis of key infrastructure technology)

中心差分法求解动力学响应，可以尝试一下，个人觉得不错(The central difference method for solving structural dynamics problems)
