The error in the estimate of the kth eigenvalue of a regular Sturm-Liouville problem obtained by Numerov's method with mesh length h is O(k^6h^4). It is shown that the error can be reduced to O(k^3h^4) by using one of the three versions of the exponentially-fitted Numerov method. Numerical examples demonstrate the usefulness of this approach even for low values of k.
