简单的K均值聚类函数，用于求算重心的函数，算法高效快速(Simple K-means clustering function for calculating the center of gravity function, the algorithm is fast and efficient)

An alternative to Matlab s HIST, function HISTW prevents extreme values in top and bottom percentiles of an input vector affecting the histogram s scaling, obscuring location and shape of the distribution s main mass. Limits of x and y (maximum only) axes can be set, and a marker line drawn at given x position. In contrast to HIST, bin size can be explicitly specified, and relative, rather than absolute, frequencies are plotted.

对于参数估计问题,克拉美罗界(简称CRB)为任何无偏估计量的方差确定了一个下限. 即不可能求得方差小于下限的无偏估计量,并为比较无偏估计量的性能提供了一个标准. 本程序对CLRB（克拉美罗下界）进行了描述，预留了参数。 希望能对同志们提供帮助。(For the parameter estimation problem, Cramer-Rao bound (referred to as CRB) for any unbiased estimator of variance to determine a lower limit that can not be obtained is less than the minimum variance unbiased estimator and unbiased estimator for comparing the performance of provides a standard procedure for this CLRB (Cramer-Rao lower bound) for a description of the reserved parameters. Hoping to help comrades.)
