代码说明：
全波形反演，一纬，二维 Frequency-domain full-waveform tomography for visco-acoustic media. ! # ! # Program FWT2D is a massively parallel code for distributed memory platform ! # which performs frequency-domain full-waveform inversion of seismic data [10,11,12,13]. ! # The program is more specifically designed for wide-angle or global offset data !!!!!!!!!更特别设计 ! # (that is, for any acquisition system involving dense wide-aperture acquisitions ! # and for which sources share a significant range of receivers spanning over large ! # offsets). The inversion looks for the P-wave velocity only. However, heterogeneous ! # density and attenuation can be provided for the forward modeling. ! # The inversion relies on a classic iterative steepest descent algorithm [1,2]. Iterations !!!!!!反演依赖于经典的迭代最速下降法 ! # are performed in a non linear way which means that the final model at
