Mixed High-order Compact Difference Scheme for Solving the Two-point Boundary Value Problem
摘要
Abstract
Compact scheme is divided into explicit compact scheme and implicit compact scheme.With the help of two kinds of compact scheme ideas,a mixed high-order compact difference scheme is constructed for solving the two-point boundary value problem.The scheme uses three-point unknown function values and theirs first-order derivative values.The first-order derivative is solved by the Padé scheme.The proposed scheme is overall fouth-order accuracy.Numerical experiments are given to prove the efficiency and dependability of the present scheme.关键词
