L. Greenberg et M. Marletta, ALGORITHM-775 - THE CODE SLEUTH FOR SOLVING 4TH-ORDER STURM-LIOUVILLEPROBLEMS, ACM transactions on mathematical software, 23(4), 1997, pp. 453-493
We describe a new code (SLEUTH) for numerical solution of regular two-
point fourth-order Sturm-Liouville eigenvalue problems. Eigenvalues ar
e computed according to index: the user specifies an integer k greater
than or equal to 0, and the code computes an approximation to the hth
eigenvalue. Eigenfunctions are also available through an auxiliary ro
utine, called after the eigenvalue has been determined. The code will
be made available through netlib.
