摘要
针对一类二维抛物型方程,建立了一个在空间和时间方向上均具有二阶精度的有限差分格式,并分析其稳定性.比较以往算法,该格式具有精度相对较高,无条件稳定等优点.
A finite difference scheme with accuracies of second order in space and in time was constructed for a kind of two-dimensional parabolic equation, the stability was analysised. Compared to traditional algorithms, the scheme have high accuracy and unconditional stability.
