A general conservative eighth-order compact finite difference scheme for the coupled Schrödinger-KdV equations

In this paper, we present a general conservative eighth-order compact finite difference scheme for solving the coupled Schrödinger-KdV equations numerically. The proposed scheme is decoupled and preserves several physical invariants in discrete sense. The matrices obtained in the eighth-order compac...
