Effect of Hyperbolic Interpolation in the Finite Element Solution of an Eigenvalue Problem

Abstract

In this paper hyperbolic interpolation has been used instead of Lagrange interpolation in solving an eigenvalue problem by using finite element method. The result shows that there is a good agreement between the eigenvalues obtained by using hyperbolic interpolation and the exact eigenvalues. Keywords: Eigenvalue problem; finite element method; Lagrange interpolation; hyperbolic interpolation.
