代码说明:

应用背景K-均值聚类,是一种方法,矢量量化,最初是从信号处理,这是流行的,聚类分析,数据挖掘,K-均值聚类的目的是和分区和,观察到的,其中每个观察属于集群与最近的和平均,服务为一个和原型的集群。这个结果在一个分区的数据空间为 ;Voronoi单元关键技术•特别是在使用启发式的方法时,如劳埃德的算法是比较容易实现和应用,即使在大数据集。因此,它已成功地用于各种主题,包括市场细分, ; ; ;计算机视觉,地质统计学,[ 21 ]  ;天文学 ;和 ;农业。它经常被用来作为一个预处理步骤的其他算法,例如,找到一个起始配置。

    光子晶体的能带图计算,其实质就是电磁本征值(复矢量场)的问题。利用平面波展开磁场,引入f(r)=1/eps(r),再利用倒格矢G将f(r)展开,将两者代入光子晶体的支配方程,最后得到一个平面波展开的方法的线性方程组,最终转化为求解其特征值向量的问题。(Energy band diagram of the photonic crystal, its essence is the electromagnetic eigenvalues ​ ​ (complex vector field).The linear plane wave expansion magnetic field, the introduction of f (r) = 1/eps (r), re-use reciprocal lattice vector G will expand f (r), the two substituted into the governing equations of the photonic crystal, and finally get a plane wave expansionequations, and ultimately into solving the problem of its eigenvalues​ ​ .)
