非线性薛定谔方程的五种差分格式

Five difference schemes of nonlinear Schrdinger equation

给出了非线性薛定谔方程的5种差分格式,并且分析了这些格式的局部截断误差以及稳定性和收敛性.并且用数值实验比较了它们的截断误差和运算速度.

Five kinds of difference formats of nonlinear Schrdinger equation have been presented.The analysis of local truncation error,stability and convergence of these schemes have been gained.Their truncation error and speeds have also been compared with numerical experiments.
