Nature of problem:
For nuclear, atomic physics and other fields of physics in solving eigenvalue problem for Schrodinger equations with unsymmetrical potentials, in case an efficient and speedy procedure is desired.

Solution method:
Using the spline function and WKB approximation in Milne's method for eigenvalue problems of Schrodinger equations with unsymmetrical potential, we support a program package MEV3.
