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)

计算岩石表面裂隙宽度并求取其表面粗糙度系数(Calculate the rock surface crack width and strike the surface roughness coefficient)

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.)

单元刚度矩阵，用于计算三单元刚度矩阵，输出刚度矩阵(Element stiffness matrix is ​ ​ used to calculate the three-element stiffness matrix, the output stiffness matrix)

说明：  地球处理多边体的重磁异常的正演，主要是地球数据处理的课程的实验项目2(The forward modeling of gravity and magnetic anomalies in the earth s processing of the multilateral body is mainly the experimental project of the earth data processing course 2)

说明：  用C语言编写多元线性回归方程，写得不好的地方请指教！(Using C language multiple linear regression equation, where poorly written, please advice!)

fluent 软件动网格计算的CAS文件和二次开发程序。用来计算一个蜜蜂翅膀摆动时周围流畅的变化。(fluent moving grid computing, software, documents and secondary development of CAS procedures. Used to calculate the wings of a bee when swinging around the smooth changes.)

可以实现十几位整数的四则运算，效率也较好(Four operations can be more than a dozen integer,and the efficiency is better)
