If the coefficient matrix of the system of linear algebraic equations is strictly diagonal dominant or irreducible weakly diagonal dominant, the stopping test formulas of the iterative method x(s+1)=Gx(s)+K for solving PDE is proposed in this paper.

 
  • 當線(xiàn)性代數方程組的系數矩陣是嚴格對角優(yōu)勢或不可約弱對角優(yōu)勢時(shí),本文給出了使用迭代法u~(s+1)=Gu~(s)+K解偏微分方程時(shí)的終止檢驗公式。
