无网格伽辽金方法2d源程序
无网格伽辽金方法计算源程序(线弹性2D问题)-EFGM source method (2D linear elastic problems)无网格法(Mesh-less method) 无网格方法(Mesh-less method)是在数值计算中不需要生成网格,而是按照一些任意分布的坐标点构造插值函数离散控制方程,就可方便地模拟各种复杂形状的流场。该法大致可分成两类:一类是以Lagrange方法为基础的粒子法(Particle method),如光滑粒子流体动力学(Smoothed particle hydrodynamics,简称SPH)法,和在其基础上发展的运动粒子半隐式(Moving-particle semi-implicit,简称MPS)法等;另一类是以Euler方法为基础的无格子法(Gridless methods),如无格子Euler/N—S算法(Gridless Euler/Navier-Stokes solution algorithm)和无单元Galerkin法(Element free Galerkin,简称EFG)等。无网格方法可以方便地利用坐标点计算模拟复杂形状流场计算,但不足之处是在高雷诺数流动时提高数值计算精度较困难。无网格方法中比较常见的还有径向基函数方法(Radious Basis Function),主要使用某径向基函数(如(MQ)f(r)=r^5)的组合,来逼近原函数。吴忠敏院士在这方面有比较突出的工作。

k-means算法实现
数据挖掘 聚类算法 k-means的实现,改进了一些初始中心选取的方法。聚类算法是最大化类间差异,而最小化类内部差异的算法,k-means比较经典,但是缺点是需要指定k值,并且聚类结果与初始中心有很大的关系,通过改善聚类初始中心选取的方法,能够得到更加稳定的聚类结果
