最新版的oofem 可以自己加入一些材料模型 版本更新速度也算快(latest version of oofem )

计算复序列的分裂基快速傅里叶变换，分裂基快速算法是将基2和基4分解组合而成。在基2M类快速算法中，分裂基算法具有最少的运算量，且仍保留结构规则、原位计算等优点。(Calculate complex sequence of split radix fast Fourier transform, fast algorithm is to split the base base 2 and base 4 decomposition combination. 2M fast algorithm in the base class, the split-based algorithm has the least amount of computation and structural rules remain in situ calculation and so on.)

用mfc实现计算器的基本操作，支持键盘输入，并保留xp风格,可计算平方，幂，时间显示等操作(With mfc achieve the basic operation of the calculator, support for keyboard input, and retain xp style, calculates the square, power, time display and other operations)

用c++实现m次多项式的曲线拟合，改程序简单易懂，可读性强(it s easy)

交错网格声波方程交错网格有限差分地震波场计算波场正演模拟。 (The CalCulation of the SeismiC Wave一 fieldwith Staggered-grid Finite difference Sheme )

用C++实现排队论中M/M/1模型。简单方便。(Using C++ implementation in the M/M/1 queuing theory model. Easy and convenient.)

改进的冒泡排序的VC++源程序，希望大家能够从中受益！(improved Bubble Sort VC source, we hope to benefit from!)

复数的四则运算完整版，包括加减乘除，阶乘，开方等。。。(The plural arithmetic full version,, including addition, subtraction, multiplication, and division factorial, prescribing, etc...)

用于计算大物实验中常用的平均值和不确定度。(a simple tool to calculate average of input values.)

矩量法仿真电磁辐射和散射的源代码（c++） (Moment Method Simulation of electromagnetic radiation and scattering of the source code (c++))
