A program for performing a numerical integration of the Schrödinger equation

Title of program: DIFEQ Catalogue Id: ACCC_v1_0 Nature of problem Differential equations of the form psi''(x) + (lambda-V(x))psi(x)=0, x in range (a,b) with boundary conditions psi(a)=psi(b)=0 are solved. The main purpose of this paper is to present a perturbative procedure for the calculations of approximate eigenvalues of the Schroedinger equation.
