差分法

把 Maxwell 方程式在时间和空间领域上进行差分化。利用蛙跳式(Leap frog algorithm)--空间领域内的电场和磁场进行交替计算，通过时间领域上更新来模仿电磁场的变化，达到数值计算的目的。(The Maxwell equations in time and space on the field differencing. Using the leapfrog (Leap frog algorithm)- Space field for alternating electric and magnetic fields calculated by the time domain electromagnetic field is updated to mimic the changes to achieve the purpose of numerical calculation.)

求实对称矩阵的特征值特征向量，内有读入数据文件。(Realistic symmetric matrix eigenvalue eigenvector, there are read into the data file.)

能够非线性函数的曲线拟合，包括一个Matlab的m文件和存有实验数据的txt文件。(Nonlinear function to the curve fitting, including a Matlab m-files and there are experimental data txt file.)

说明：  非常好的卡尔曼滤波学习程序。文章中有原题，有解题步骤，有实现程序。适合卡尔曼学习过程中的人。(Very good learning process Kalman filter. The article in the original title, there are problem-solving steps to achieve the procedure. Kalman learning process for people.)

说明：  上数据挖掘课的课件，是EM算法的，其中还包括最大似然值，最大似然估计，以及cluster(data mining,EM Algorithm ,Likelihood, Mixture Models and Clustering )

lu分解矩阵求逆... =========== 紫薯紫薯...(Matrix LU decomposition inversion)

此为基于图像配准的傅立叶变换源代码，已精心调试过，请放心使用.(This is the image registration based on the Fourier Transform source code, has been painstakingly debugging, please rest assured that use.)

计算流体力学有限体积法程序开源代码改进版本，增加了湍流模型(An improved Edition of open source computational fluid dynamics finite volume method program, increased turbulence model)

求解线性方程组，高斯消去法精确求解出任意个方程组的解，(Solving linear equations, Gaussian elimination exact solution,)

这是一段杆塔建模的命令流，可用于ansys有限元分析(This is a tower of order flow modeling, finite element analysis can be used to ansys)
