A FINITE-ELEMENT ESTIMATE WITH TRIGONOMETRIC HAT FUNCTIONS FOR STURM-LIOUVILLE EIGENVALUES

[摘要] The computation of eigenvalues of regular Sturm-Liouville problems is considered. Numerical results show that the error of the kth eigenvalue obtained by the finite-element method with trigonometric hat functions and mesh length h is of the same order as the one obtained with the linear hat functions together with a simple asymptotic correction technique of Paine, de Hoog and Anderssen (1981).
