kmeans的程序，用欧式距离对80个对象进行分类(a kind of procedure ralated to the algorithm of Kmeans )

经典的标量JA 模型的代码，非常适合磁滞模型初学者 我给出了两种实现方式的代码 一个用固定点迭代实现，可以容易变成c语言 另一个使用simulink 实现，可以加到控制图中作为一个子函数(the code is programmed following the classical paper of D.Jiles ,fellow of IEEE. The JA model is great and innovative work in magnetic material.)

MATLAB如何定义函数文件，对于使用matlab时，当发现没有合适的库函数，就需要自己定义函数了，此文档可帮助你(How MATLAB function definition file, for the use of matlab, when found no suitable library functions, you need to define your own functions, and this document can help you)

1.duishuzhengtai：产生对数正态分布 2.gaussian：产生数据量为n的两个相互独立高斯分布y1、y2 3.junyun：自定义 0-1的均匀分布，n代表数据量，一般要大于1024（蒙特卡罗） 4.ruili：瑞利分布,m是瑞利分布的参数,n代表数据量,n一般要大于1024 5.kaifeng：产生开丰分布，其中m代表开丰分布的自由度，n表示产生的点数量 6.tfenbu：本函数产生自由度为m，数据量为n的t分布。 7.weibuer：a=1时,是指数分布；a=2时,是瑞利分布(1.duishuzhengtai: generating lognormal 2.gaussian: generating a data quantity n of two mutually independent Gaussian distribution Y1, Y2 3.junyun: custom uniform distribution of 0-1, n represents a data amount, generally large in 1024 (Monte Carlo) 4.ruili: Rayleigh distribution, m is a parameter of the Rayleigh distribution, n representative of the amount of data, n is generally greater than 1024 5.kaifeng: generating open abundance distribution, wherein m represents an open-abundance distribution freedom of degrees of freedom, n is the number of points generated 6.tfenbu: This function generates m, the amount of data for n t distribution. 7.weibuer: a = 1, the exponential distribution a = 2, is a Rayleigh distribution)
