Schrdinger型方程的一类半隐式差分格式

A kind of semi-implicit difference schemes for Schrdinger type equation

讨论了Schr dinger型方程Ut=iUxx的一类半隐式差分格式,这些格式实际上是可以显式求解的.通过傅里叶分析,给出了它们的稳定性条件.

In this paper, a kind of semi_implicit difference schemes for Schrdinger type equation Ui=iUxx are discussed. In fact, these schemes can be solved by changing them into explicit forms with the given stability conditions. 
