Solving Sturm--Liouville eigenvalue problems. [SLEIGN, for CDC 6600 computer]

Technical Report ·
OSTI ID:7250095

A code SLEIGN is presented to compute the eigenvalues and eigenfunctions of the Sturm--Liouville problem (d/dx) (p(x) (dpsi(x)/dx)) + (q(x) + lambdar(x)) psi(x) = 0 on (a,b), A/sub 1/psi(a) + A/sub 2/p(a)psi'(a) = 0, and B/sub 1/psi(b) + B/sub 2/p(b)psi'(b) = 0. Infinite intervals and singularities of the coefficient functions at endpoints are handled automatically. An estimate of the true error in the eigenvalue is obtained with each eigenvalue. This report provides a general description of the algorithm, its implementation, and performance. It also describes and exemplifies the use of the subroutine SLEIGN. 1 table.
