中文说明：该程序用matlab语言编写，用于面波层析成像，通过tau-p变换得到瑞利频散曲线，然后利用频散曲线进行反演得到s波速度
English Description：
This program is written matlab language , and it is used for surface wave tomography ,you could get the rayleigh dispersion curve by tau-p transform ,and then we could use the dispersion curve to do the inversion to get the s velocity
