代码说明:

  函数作用: cwstd.m——用综合标准化法标准化矩阵 Cwfac.m——计算相关系数矩阵,计算特征向量和特征值,对主成分进行排序,计算各个特征值的贡献率,挑选主成分(贡献率达与85 ),输出主成分个数,计算主成分载荷 Cwscore.m——计算各主成分得分,综合得分并排序 Cwprint.m——读入数据文件,调用以上三个函数,并输出结果 原始数据:存储在src.txt中是一个30×8的矩阵 敲入命令: (PCA)

    matlab的pde工具箱很薄弱,同时只能处理有限复杂度的问题,利用comsol强大的有限元分析与多物理场的耦合性,解决相当完美。 matlab与多物理场有限元软件的结合,本程序需要安装matlab7.0以上以及comsol multiphysics 3.0以上版本,建立客户端后可以方便的利用matlab控制有限元软件,进行建模计算。 本程序描述的是点电荷周围的电场以及电势。适合于初学者(The pde matlab toolbox is very weak, and can only handle a limited complexity of the problem, by using comsol powerful finite element analysis and multi-physical field coupling to solve quite perfect. matlab and multi-physics finite element software combination, the above procedure to install matlab7.0 and comsol multiphysics 3.0 or later, after establishing the client can easily control the use of matlab finite element software to model calculations. This procedure describes the electric field around a point charge and the electric potential. Suitable for beginners)
