Abstract
In this paper, we are concerned with the solution of a class of boundary value problems −y″+f(x)y=λy, y(0)=0, y(∞)=0, where f(x) monotonically increases to infinity as n increases to infinity. We use finite difference scheme to reduce the system to an equivalent system of an infinite linear algebraic eigenvalue problem. We give a precise error analysis for the eigenvalues of the approximate system and an error analysis for the continuous system under the condition that |yⁱ ̌(x)| is bounded. The theory is applied to compute the eigenvalues when f(x)=x² for which explicit solutions are known. Copyright © 2007 Elsevier.
