数据挖掘讲义第六章聚类分析,PDF文件大小约520K(Data mining handout Chapter 6 clustering analysis, PDF file size is about 520K)

最小二乘法拟合进行n次多项式拟合，N用来控制拟合的次数，例如N=5时进行4次多项式拟合，还回的是拟合系数(Least squares fit polynomial n times, N is used to fit the number of control, e.g., N = 5 When quartic polynomial fitting, further back are fitting coefficients)

该程序用fortran90编写，时域有限差分（FDTD)中的分裂场方法。解决了斜入射情况下周期结构的电磁散射问题。(FORTRAN90 prepared with the program, finite difference time domain (FDTD) method of splitting the market. Solved the case of oblique incidence of electromagnetic scattering from periodic structure issues.)

EKF uKF的matlab工具箱，适合做非线性滤波的仿真计算。(EKF uKF the matlab toolbox for nonlinear filter to do the simulation.)

偏微分方程的数值解法，简单的离散 变分以及求解过程(Numerical solution of partial differential equations, the simple and the solution process of discrete variational)

5个子函数，包括格拉布斯剔除异常值函数，牛顿插值法函数，拉格朗日插值法函数，希尔排序函数，莱以特准则剔除异常值函数，函数方便移植。(5 sub-functions, including functions Grubbs outliers removed, Newton interpolation function, Lagrange interpolation function, Hill sort function, Levin special criteria to exclude outliers, function to facilitate transplantation.)

运用物理光学法和矩量法计算带罩天线的远场辐射(The use of physical optics method and moment method with cover antenna far-field radiation )

arithemetic code on visual c++

时间积分算法在有限元动力学中的应用，可以计算结构的瞬态响应(This class implements a Newmark beta-gamma predictor-corrector time inte- gration scheme, with accelerations as primary unknowns. .A Newmark scheme assigns to the dofs the following 5 unknowns : - the displacement d and its predictor D - the velocity v and its predictor V - the acceletion a . Their expressions are calculated by the dofs in class Dof.)

变增益PID算法的c++实现，目前PID算法较多的是c代码写的，这里上传一个C++的(Variable gain PID algorithm c++ to achieve, the current is more PID algorithm code written in c, where a C++ From the)
