The computation of eigenvalues of Sturm-Liouville problem with t-periodic boundary conditions is considered. Using the Richardson extrapolation based on the finite difference, the accuracy of the eigenvalues are improved. Numerical results demonstrate the usefulness of the correction. (c) 2004 Elsevier B.V.
