plot the contour z of an image source code

说明：  用matlab实现的曼彻斯特编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的郭文斌的通信原理课件上的形状一模一样。(Manchester encoding with a matlab implementation. 50 duty cycle (adjustable). Draw time-domain waveform and frequency domain power spectral density. The results with the Beijing University of Posts and Telecommunications of the GUO of communication theory on the shape of the same courseware.)

仿真SMI（DMI）算法性能，观察采样快拍数对波束图的影响、接收信号中不包含、包含信号功率逐渐加大对波束图的影响(Simulation SMI (DMI) algorithm performance, the number of snapshots observed sampling effects on the beam diagram, the received signal does not contain, include the gradual increase of the signal power of the beam map)

本代码对OFDM中载波频偏对系统误码率的影响进行了全面的仿真和比较，对加深对OFDM载波同步技术的理解很有帮助(The code in OFDM carrier frequency offset the impact of the system bit error rate of a comprehensive simulation and comparison to deepen the understanding of OFDM carrier synchronization helpful)

路基导航系统罗兰信号模拟代码，matlab实现，可以方便得设置各种参数(Roadbed navigation system Loran signal simulation codes, matlab realize, you can easily configure various parameters)

matlab subroutine makes the global stiffnes matrix assebling of quadrilateral elements

k均值进行聚类分析，把二维模式矢量分成三、四类，用SOFM算法(K-means clustering analysis, the two-dimensional pattern vector is divided into three or four classes, using SOFM algorithm)

Hausdorff dimension matlab code

以Matlab为应用背景，比较详细地介绍了根轨迹图的制作。(Examples on Root Locus Plot.)
