A high-speed method for eigenvalue problems. III: Case of unsymmetrical potentials in Milne’s method A new version of MEV2 by Milne’s method is presented for eigenvalue problems 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 Schr”odinger equations. (Source:
