用最简单的方法来实现kmeans聚类，具有不错的效果(The most simple way to achieve kmeans clustering, with good results)

用于曲线拟合的matlab程序 属于基本的内容 但是很好用(curve fitting with matlab)

C语言写的基2fft算法，测试过了结果，比matlab的结果精度还是稍差(fft algorithm in C language.Have testd the result.)

说明：  均匀线阵常规波束形成仿真 假设条件 窄带(单频)； 远场平面波(目标距离远大于阵长)； 无多途干扰； 信号无多普勒，无畸变。(Simulation of conventional beamforming of uniform linear array)

这个程序是幅值谱中校正频谱峰值的比值校正法，可以自设定校正谱峰值的个数，比值校正法还可以校正相位，校正的结果很准确(This procedure is correction of the amplitude spectrum of the ratio of the peak spectrum correction method, correction can be set from the number of spectral peaks, the ratio correction method can also be correction phase, the results of very accurate correction)

program to find the k - nearest neighbors (kNN) within a set of points. Distance metric used: Euclidean distance
