说明：  迭代算法中的多重网格计算程序Visual C++原代码(iterative algorithm of multiple grid computing procedures Visual C source code)

数值计算实例，主要有LU分解，龙格库塔法，高斯分解法，欧拉法，曲线拟合，曲线插值(Numerical example)

本程序可以实现在交错网格条件下的三维有限差分正演模拟(This procedure can be achieved under the conditions of the staggered grid finite difference forward modeling)

说明：  邓肯张在ansys中的二次开发，适合于土体有限元分析(second development of duncan-zhang in ansys,it s be used to ansys)

计算偏心圆导热计算以及同位网格上的SIMPLE算法 (Calculating thermal calculations and eccentric position on the grid with SIMPLE algorithm)

由散点插值生成等值线,并且提供颜色选择工具,共有三种插值方法(Generating isolines from scattered interpolation and providing a color selection tool, there are three interpolation methods)

C 语言，模拟流体相平衡过程，得到混合气体平衡态以后的工况参数(C language to simulate fluid phase equilibrium process, to obtain a mixed gas equilibrium after working parameters)

我自己用c语言写的64点基4FFT算法，在visual c++ 6.0环境下编译通过。同matlab结果一致。(My own use C language to write the 64 based 4FFT algorithm, in visual c++ 6 compiler environment through. Results consistent with matlab.)

用吉尔方法积分一阶微分方程组的初值问题。(Gill method with integral equations of first order initial value problem.)

C语言矩阵求逆模块,输入矩阵调用此模块即可求出对应的逆矩阵(C language matrix inversion module)
