说明：  An Implementation of Karmarkar s Algorithm for Linear Programming

用MATLBA实现聚类，简单好用，适合初学者(Clustering in with MATLBA, easy to use, suitable for beginners)

filter滤波器，由Matlab 编译完成(filter)

仿真人体的心肺活动信号，在I,Q空间获得该信号的I-Q曲线(simulate the heart and lung beat, show the I-Q curve )

对信号进行时域特征提取，个人已使用，感觉很不错！(The time domain feature extraction of the signal, the individual has been used, I feel very good!)

matlab的nmf工具箱，很有用。希望大家下载拥有。(nmf the matlab toolbox, useful. Hope you have downloaded.)

说明：  关于瑞利衰落的一段很实用的代码。特别在BPSK调制中对于学习通信方面的同学很有帮助。(Rayleigh fading on a very useful code. BPSK modulation, especially in communications for students to learn helpful.)
