摘要
本文结合多重网格和预处理迭代法,提出了求解二维抛物型方程初边值问题的一种很有效的方法,通过巧妙构造预处理迭代矩阵,从而显著减少迭代矩阵的条件数,加快了迭代收敛速度,提高了求解效率。
Based on combining of muhiple grids and pretreatment iterative method, this paper puts forward a very effective method of solnting two-dimensional parabolic equation initial-boundary value problem. Through clever constructing pretreatment iterative matrix, the number of iteration matrix condition is reduced significantly, the convergence speed is accelerated and the solution efficiency is improved.
