摘要: 讨论了满足边界条件y(a)=A 和y(b)=B 的二阶非线性常微分方程y″=f(x,y)的六阶三对角差分法,并从理论和实际计算证明了该方法的六阶收敛性。

Abstract: This paper presents a new sixth order finite difference method to solve the second order nonlinear differential equation y″=f(x,y),subject to the boundary conditions y(a)=A,y(b)=B.The sixth order convergence of this method has been proved by theoretical deduction and actual calcu- lation.
