9/7小波图像滤波，二维小波滤波快速分解重构(9/7 wavelet image filtering)

说明：  三分之一倍频程程序，信号处理必备，请自用下载(One-third octave program, self-download)

主要是异步通讯编程,C语言,大家可以看一下,以提高自己的水平,一起努力(Mainly asynchronous communication programming, C language, we can take a look, in order to improve their level, work togethe)

纯C写的小型通用数据库代码，研究数据结构很不错的参考实例，模拟交互式的SOL的基本功能:动态建表,组合查询,删除,添加,更新、支持的数据类型为:char(字符型) int(整数型) double(浮点型) string(字符串型)。压缩包内附有设计PPT，学习C语言底层很好的例子，运行时请打开CMD命令提示符环境，示例可新建、删除数据库等操作。

说明：  奇异值是信号去噪的常用方法，对非线性非平稳信号的分析产生了重大影响。(Singular value is a common method of signal denoising, which has a great influence on the analysis of non-linear non-stationary signal.)

可以对操作系统的注册表进行读、写、删除操作-The registry of the operating system can read, write, delete

求解NS方程的各种rans方法及直接数值模拟方法介绍 很好的PPT(A very good solver introduction of the ns equation，rans method, dns.)

矩形孔菲涅尔衍射模拟及圆形孔菲涅尔衍射模拟(Fresnel diffraction simulation of rectangular aperture and circular aperture)

刘金琨编著的《滑模变结构控制matlab仿真(第三版)先进控制系统设计方法》,《滑模变结构控制matlab仿真(第三版)基本理论与设计方法》MATLAB程序，滑模控制第三版上下部MATLAB程序代码；刘金琨滑模控制第三版上下部最新程序，对照程序可以复现书中的仿真图(Matlab simulation for sliding mode control edited by Liu Jinkun "(Third Edition)" the design method of the advanced control system, "matlab simulation for sliding mode control (Third Edition)" the basic theory and design method of sliding mode control MATLAB program, version third on the lower MATLAB code; Liu Jin Kun sliding mode control version third upper and lower part of the new procedures, the control program can reproduce the simulation map in the book)

配电网状态估计相关仿真资料，大家可以借鉴一下(Distribution network state estimation related simulation data, we can draw on)
