用matlab编写的cholesky分解程序，希望对大家有些帮助(Matlab prepared using Cholesky decomposition procedures, in the hope that some U.S. help)

用VBA在Excel里实现分级计算，实现通过年终奖和月收入计算个人所得税的功能。数据为2012年最新的标准，对于会计电算化人员有非常强的实用性。(VBA in Excel to achieve grade calculated to achieve the functionality of the calculation of personal income tax through the end of the year Award and the monthly income. The data for 2012 the latest standards, computerized accounting personnel have a very strong practicability.)

说明：  并联机器人MARALAND,其数值解及解析解，正解和逆解以及雅可比矩阵及动力学问题分析(Parallel robot maraland, its numerical solution and analytical solution, positive solution and inverse solution, Jacobian matrix and dynamics analysis)

包括了一个二维的方柱FDTD散射程序，入射波为TM模式，方柱无限长，等效为二维问题(Includes a two-dimensional square cylinder scattering FDTD procedures, incident for TM mode, infinite square cylinder, equivalent to two-dimensional problem)

改程序是计算出金属表面等离子体直波导的有效折射率随波长和传输长度随波的两色散曲线，另外给定Drude-Lorentzia模型参数给定后，还可以求解介电常数以及画出相应实部和虚部的曲线(This programer is used to calculate Ag relative dielectric constant accroding to the Drude-Lorentzia and sovle the transcendental equation for even illumination. At the same time,it can draw the diagram of relationship between the dispersion curve and the Transmission with the length. )
