求解量子力学的薛定谔方程

%> The file <wellbd.m> calculates bound states in spherical square 
%> potential well of finite depth.  The radius is chosen in CW, value A, thus:
%> V(r) = V < 0 for r < A, = 0 for r > A.  V is chosen in CW.
%> The bound state energy levels are found from the known analytical formulas 
%> involving Bessel functions by an automatic numerical search for the solutions 
%> of a transcendental equation. This search may miss weakly bound states.
%> The accuracy is largely determined by the parameter NN, the number of energy 
%> lattice points. The analytic formulas can be found e.g. in Messiah Sec. IX.10.
%> Uses standard Bessel function program of MATLAB, and <findzero.m>.
