T. Yano et al., A HIGH-SPEED METHOD FOR EIGENVALUE PROBLEMS .3. CASE OF UNSYMMETRICALPOTENTIALS IN MILNES METHOD, Computer physics communications, 81(3), 1994, pp. 409-424
A new version of MEV2 by Milne's method is presented for eigenvalue pr
oblems of linear differential equations of Sturm-Liouville-type. This
version MEV3 enables one to calculate eigenvalues and eigenfunctions,
for instance, for the case of unsymmetrical potentials in Schrodinger
equations.
