Two computer programs (FGHEVEN and FGHFFT) for solving the one-dimensional Schrodinger equation for bound-state eigenvalues and eigenfunctions are presented. Both computer programs are based on the Fourier grid Hamiltonian method (J. Chem. Phys. 91(1989) 3571). The method is exceptionally simple and

A local grid method is proposed for computing the bound state eigenvalues and eigenvectors of multidimensional systems. The connection of the proposed methods with the one-dimensional Fourier grid Hamiltonian method is clarified. Results obtained with three different 2D Hamiltonians are compared wit
Eigenfunctions and eigenvalues of the Schrtiinger equation are determined by propagating the Schrodinger equation in imaginary time. The method is based on representing the Hamiltonian operation on a grid. The kinetic energy is calculated by the Fourier method. The propagation operator is expanded i
