barrier.m

求解量子力学的薛定谔方程

%> The file <barrier.m> calculates the energy dependent transmission 
%> coefficient for a 'square' barrier (of either sign!) in 1D. 
%> The coefficient is first calculated using the Numerov algorithm.
%> This result is then compared with the known analytical formula given 
%> e.g. in Messiah Ch III. The transmission coefficient is displayed as 
%> a function of the energy renormalized by the barrier height.
