经典的可编程添加模块的面向对象的有限元程序代码(C++ code for OOFEM based on multi-systems)

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.)

实现卡尔曼滤波算法，可以进行参数估计、插值、滤波和预报(The Kalman filter algorithm, parameter estimation, interpolation, filtering and prediction)

利用快速解耦法进行电力系统潮流计算，对配电网进行潮流计算(Use of PQ decomposition method for the electric power flow calculation system)

三次样条插值c++头文件，一些头文件，非常好(Cubic spline interpolation c++ header files, some header files)

本例实现了插值函数，将不同次数的插值进行了显示，防止了龙格现象，研究生一般以此题为作业。(The cases to achieve interpolation function, the number of different interpolation were shown to prevent the Runge phenomenon, in order to graduate generally entitled operations.)

非负矩阵分解的matlab代码，内容全！希望对大家有用(Non-negative Matrix Factorization of matlab code, the contents of the whole! Hope useful for everyone)

本人编写的基于最小二乘法的圆拟合程序，可直接下载使用。(I prepared the least squares method based on circle fitting procedures, can be directly download.)

利用MATLAB实现了16位快速傅立叶变换，并与自包含函数进行了比较。(The 16-bit Fast Fourier Transform is realized by using MATLAB and compared with the self-contained function.)

可用于层次分析法比较评价，主函数输入初始矩阵，调用层次分析函数(It can be used for comparative evaluation of analytic hierarchy process. The main function input the initial matrix and call the analytic hierarchy process function.)
