%> This is <bound1d.m)!
%> This file calculates bound state eigenvalues/functions for a 
%> Schroedinger particle in 1D using the Fourier Grid Hamiltonian
%> method in the function file <fgh.m>. This means: a discrete lattice
%> approximation of the Hamiltonian and the use of the MATLAB <eig> 
%> routine to find eigenvalues and eigenvectors. 
%> The calculation must be done in an interval sufficiently wide such
%> that the exact eigenfunctions are essentially zero outside. 
%> The WKB approximation is used to get a first estimate of the
%> number of solutions. 
%> Uses <fgh.m>, <wkb.m> ...
