本文件里面是Costas环跟踪信号的几幅图，对于加深理解有所一定的帮助。()

This is the solution of chapter 12 example 1 from advanced engineering electromagnetics by Constantine A. Balanis.The solution is based on MATLAB.

matlab code for radio-altimater

说明：  K-MEAN:经典K均值算法,适用领域：语音识别，图像识别(K-MEAN: classical K-means algorithm, the application areas: speech recognition, image recognition)

说明：  一种分簇算法，适合用于数据聚类，将相似的点集合到一个簇内。(Its a new method of clustering,useing this clustering algorithm ,you can obtain a cluster which is stable )

这个程序关于语音信号的消噪，实现了一个基于递归最小二乘法的噪声抵消器(This program about the speech signal de-noising, implements a recursive least squares method based on a noise canceller)

遥感影像变化检测经典算法(IR-MAD、MAD、CVA、PCA),另外进行了算法的Demo和精度等计算评价（OA、Kappa、AUC、ROC）(Remote sensing image change detection classical algorithm (IR-MAD, MAD, CVA, PCA), were additionally algorithms and calculation accuracy Demo Assessment (OA, Kappa, AUC, ROC))

Gert Cauwenberghs写的一个增量型支持向量机，非常有用的(Gert Cauwenberghs wrote a incremental support vector machive. It is very useful for learning about it.)

DIGITAL water marking

说明：  Crank-Nicolson法求解poisson方程，矩形区域，狄利克雷边界。(Crank-Nicolson method for solving poisson equation, rectangular area, Dirichlet boundary.)
