A generalized finite difference / interpolation algorithm using Lagrange polynomials from B. Fornberg (1998).

fwi-using-temporal-fourth-fd-modelling

These codes are used to complete elastic full waveform inversion using temporal fourth-order FD modelling. In order to accelete the algorith, GPU-based versions are privided here. What's more, the GPU shared memory is used in block level and the efficiency improvement is about 10%~15% on GTX 750ti, where efficiency improvement is dependent on the length of FD orders.
