摘要
用改进的JGS迭代方法求解抛物型方程,构造了一种新的并行计算格式,并证明了新算法是绝对稳定的、显式的,截断误差达到O(τ+h2).数值实验结果与理论分析相符.
The improved JGS iterative method was used to solve parabolic equations,and a new parallel method was constructed.We prove that this method is absolutely stable and explicit,and its truncation error reaches O（τ＋h2）.The numerical experimentation agrees with the theory analysis.
