method based on Runge Kutta method. The shooting method is commonly used,but the calculation
time is long. When the boundary conditions are more complex or more sensitive,the relaxation
method is better.In this paper,the Schrodinger equa- tion is solved by the relaxation method and
compared with the analytical solution. It is found that the numerical so- lution obtained by
relaxation method is in good agreement with the analytical solution,and the accurate solution can
be obtained quickly by relaxation method.
Key words: relaxation method; Schrodinger equation; numerical analysis
