TotalWES.m是主干程序，而DCoef和FCTforAW是里面调用的函数。TotalWES只要实现交错网格有限差分波场数值模拟，其中的FCTforAW是用来消除数值频散的。这些是实现弹性波波场模拟的程序，其它两个文件是实现声波波场模拟的程序(TotalWES.m is the backbone of the procedure, and DCoef and FCTforAW is inside a function call. As long as the realization of TotalWES staggered grid finite difference numerical simulation of wave field, which FCTforAW is used to eliminate the numerical dispersion. These are the realization of elastic wave field simulation procedures, the other two documents are to achieve the sound the ball field simulation procedures)
