一本介绍matlab的书籍，由西安交通大学李人厚编著(An introductory books matlab, from Xi an Jiaotong University, edited by Li Renhou)

matlab code for k-means. suitable for the young programmer

网格编码8PSK系统中最佳码的研究与分析(Trellis Coded 8PSK system code to the best research and analysis)

最小费用最大流算法通用Matlab函数 基于Floyd最短路算法的Ford和Fulkerson迭加算法   基本思路：把各条弧上单位流量的费用看成某种长度,用Floyd求最短路的方法确定一条   自V1至Vn的最短路 再将这条最短路作为可扩充路,用求解最大流问题的方法将其上的流   量增至最大可能值 而这条最短路上的流量增加后,其上各条弧的单位流量的费用要重新   确定,如此多次迭代,最终得到最小费用最大流.(Minimum cost maximum flow algorithm general Matlab functions The basic idea of ​ ​ the shortest path algorithm of Ford and Fulkerson superposition algorithm based on Floyd: the cost of unit flow on the arc as a certain length of Floyd and the shortest path method to determine the one percent self-V1 to the Vn the most short-circuit and then the this Article is the most short-circuit as a can be the expansion Lu, to use solving the method of the the the problem of the maximum flow will its on the stream the amount of increased to the maximum possible values while the the the the flow of of this Article of the shortest on the road increase, the costs of the unit of flow on each arc sure, so many iterations, the final minimum cost maximum flow.)

法国人的HHT程序中，计算瞬时频率和幅值的一个函数(The French HHT program to calculate the instantaneous frequency and amplitude of a function)

this file have simple demodulation program for qpsk demodulation. it will give the bit of stream after demodulation of qpsk (quadrature phase shift keying) wave.

两束相干光的干涉强度和干涉条纹,干涉条纹用图像指令image绘制(Interference of two beams of coherent light intensity and interference fringes)

Kalman filter. Implemented in MATLAB.

说明：  matlab应用于神经网络：利用BP算法及Sigmoid函数，研究函数的逼近问题。(matlab applied to neural networks: the use of BP algorithm and Sigmoid function is to study the function approximation problem.)

This is the program for mu law companding,,,,
