%> The file <schr2.m> organizes an interactive search for eigenvalues 
%> and eigenfunctions of bound states for the 1D Schrodinger equation. 
%> The potential chosen from  <pot1.m> (it is zero outside [0,1]). 
%> NOTE that it must have some negative values!
%> Method: shooting from 0 and 1 to an interior point using Numerov algorithm.
%> BCs at 0 and 1 adapted to exponential solutions outside.
%> BCs satisfied using <numerov1.m>, solutions calculated using <numerov2.m>. 
%> ERRORS: Positive values of potential create instability problems.
%> <choice.m> allows a choice of potentials in <pot1.m>.
