Abstract:
A numerical analytical algorithm is developed for calculating the coefficients of a discrete two-dimensional elliptic equation from given eigenvalues and certain symmetry conditions imposed on the basis eigenfunctions.
Key words:partial differential equations, finite difference method, discrete elliptic equation, discrete Schrödinger equation,
