Time to depth seismic conversion Matlab function

This function converts a seismic reflection image from two-way travel time (s) to depth (km). This function is best-used when the available information is a image of a seismic reflection line (rather than, e.g. SEG-Y), and only approximate/scarce velocity information is provided.该函数可将地震反射图像从双程旅行时间（two-way travel time, s）转换为深度（km）。当可用信息为地震反射线图像（而非例如SEG-Y格式等），且仅提供近似或稀缺的速度信息时，此函数的使用效果最佳。
