Abstract:In this paper, a family of implicit difference schemes with high accuracy and absolute stability for solving one-dimensional parabolic partial differential equation are constructed by the method of undetermined parameters and their truncation errors are of order O(Δt3+Δx6). Finally, these schemes can be solved by double sweeping method.
