波动方程交错网格有限差分正演模拟

二维声波正演程序！规则网格的时间空间二阶波动方程有限差分正演，matlab编写-Two-dimensional wave medling program! matlab prepared! ! Forward seismic acoustic source

本实验应用声波方程作为正演模拟的波动方程，将所提供震源函数离散后绘图，并将给定两个二维速度 -深度模型，绘出图形。(In this experiment, we use the acoustic equation as the wave equation of forward modeling, draw the source function and draw it, and give two two-dimensional velocity depth models to draw the
