kmeans算法matlab 实现，可以处理2维数据集(kmeans algorithm matlab implementation, can handle 2-D data set)

该函数用于读取ecg信号，找到小波变换模极大序列(function to read the signals ecg find wavelet transform modulus maxima sequence)

利用wolfe-powell准则求解函数优化问题，使用不精确搜索法寻找最优步长，仿真正确。(Wolfe-powell guidelines for solving function optimization problems, the use of imprecise search method to find the optimal step length, the simulation is correct.)

本程序实现了OFDM系统的网络编码过程，包括OFDM系统子载波分配的实现(This program implements OFDM system network coding process)

说明：  对EEG信号进行形态学滤波处理，得到癫痫棘波信号(EEG signal was processed by morphological filtering to obtain epileptic spike signal)

Wiener Scalart96维纳滤波算法，是1996年Wiener发明的算法。用于跟踪噪声信号，然后通过噪声信号的频谱图，将信号进行过滤(Wiener Scalart96 Wiener filtering algorithm, Wiener 1996, invented the algorithm. Used to track the noise signal, and then the noise signal spectrum, the signal filtering)

说明：  DC MOTOR SPEED CONTROL 4
