butterworth filter for image enhancement

随机减量技术（Random Decrement Technique-RDT），其主要是利用样本平均的方法，去掉响应中的随机成分，而获得初始激励下的自由响应，(Random decrement technique (Random Decrement Technique-RDT), whose main method is to use the sample mean, remove the random component of the response, and the response to the initial excitation freedom of)

The matlab code is designed to solve linear systems of equations using the Jacobi Method.

说明：  Matlab实现夫琅禾费衍射的仿真，孔型可以任意选择(Matlab realizes the simulation of Fraunhofer diffraction)

本文件是关于阵列天线方面的方向图计算程序(This document is on aspects of array antenna pattern calculation program)

卡尔曼滤波方法，有详细的介绍资料，也有源代码，自己有一部分的编写程序，欢迎参考(Kalman filtering method, a detailed presentation materials, but also the source code, they have to program a part, welcomed the reference)

ＧＰＳ捕获跟踪新算法，DBZP实现高灵敏捕获(high sensitive acq)

利用快速傅立叶算法，实现快速沃尔什-哈达玛变换及其逆变换(Using fast Fourier algorithm, fast Walsh- Hadamard transform and its inverse transform)

说明：  DTC control of an induction motor

编写程序：基类base，有一个私有数据成员n，派生类Derived公有继承基类base，Derived中新增加一个数据成员m(Programming: the base class base, there is a private data member n, the derived class Derived inherits the base class public base, Derived add a new data member m)
