Msp. Eastham et al., USING THE SLEDGE PACKAGE ON STURM-LIOUVILLE PROBLEMS HAVING NONEMPTY ESSENTIAL SPECTRA, ACM transactions on mathematical software, 22(4), 1996, pp. 423-446
We describe the performance of the Sturm-Liouville software package SL
EDGE on a variety of problems having continuous spectra. The code's ou
tput is shown to be in good accord with a wide range of known theoreti
cal results.
