摘　　要：以带宽Toeplitz系统的快速并行解法为基础,通过秩1修正技术,把一个近似带状的Toeplitz系统化成多个带状Toeplitz方程组求解的新方法.新算法计算结构简单,具有良好的并行性能.A new fast solution for near banded Toeplitz systems was described based on fast solution to banded Toeplitz systems and rank-1 updating strategy. It turned a near banded Toeplitz equation into several banded Toeplitz systems. The structure of the new algorithm is simple, and the algorithm can be realized efficiently on parallel computer.

关 键 词：带状Toeplitz方程组 秩1修正技术 快速算法
