编写的有关数据分析的函数，可以参考！！！！！(accociation)

利用：plot，stem，grid，line，axis，xlabel，ylabel，title 等绘制阶跃函数的图像。(draw the map of step function.)

说明：  线性阵列在近场区域运用MVDR算法定位噪声源，里面有几种简单的算法(Linear arrays use MVDR algorithm to locate noise sources in near field. There are several simple algorithms in it.)

还是一些m文件集合，是一些图形编程或数值计算的集合。(m or some document assembly, some graphical programming or a collection of numerical calculation.)

做毕设用到的关于mimo-ofdm信道估计(Complete set used to do on the mimo-ofdm channel estimation)

用递推式法求解；用二分法，牛顿迭代法，迭代法求解方程的近似根(Using recursive method for solving with the dichotomy, Newton iteration method, iteration method for solving the approximate root)

从黄广斌官网下载的，添加了核函数的核极限学习机(Download the official website of Huang Guangbin, adding the kernel fucntion to Extreme Learning Machine)

包含两个文件KMEAN.h,KMEAN.CPP,使用方法非常简单，将数据存成.dat文件，即可对其进行Ｋ均值聚类(Consists of two documents KMEAN.h, KMEAN.CPP, very simple to use, the data saved as. Dat file can be K-means clustering)

说明：  采集现场轴承振动信号，计算其常用的时域指标(Collection site bearing vibration signals, calculate the commonly used time domain)

说明：  用C-C时间序列插入构造李亚普诺夫计算方法(Time series with CC Insert method of calculating Lyapunov structure)
