空间数据扩边以后做fft并在频率域延拓，可用于求重磁异常(expansion of spatial data and FFT， in the frequency domain extension can be used to find the gravity and magnetic anomalies)

说明：  MATLAB使用欧拉Euler法求解微分方程组 源程序代码(SOURCE PROGRAM CODE OF DIFFERENTIAL EQUATIONS SOURCE SOLUTION USING EULER METHOD IN MATLAB)

说明：  用LINGO求解最短路径问题，此方法为0-1规划，只适用于简单的ILP问题。(Lingo is used to solve the shortest path problem, which is a 0-1 programming method. It is only suitable for simple ILP problems.)
