论文对以tanh (x)为基础构造的Schr
The Hamiltonian systems of Schr*idinger equation wer e introduced when the differences Δ 2 and Δ 4 were used to discret t he differential operator 2[]x 2 , respectively. The symplect ic schemes were formed by using hyperbolic function tanh(x). Iterative methods w ere designed by the author to solve this symplectic schemes and gives their cond itons of convergence. The numerical example shows that the iterative methods are efficient argorithms.
