Abstract
As one of its options the software package SLEDGE estimates Sturm-Liou ville spectral density functions for problems having continuous spectr um. This paper contains the error analysis underlying SLEDGE's approxi mations: error bounds, Richardson's extrapolation, and stability analy sis. Several alternate interpolation schemes are introduced and analyz ed. An improvement to SLEDGE is suggested and tested. (C) 1996 Academi c Press, Inc.
