摘要
本文对一类具有块三对角矩阵的大型线代数方程组,给出了一种有效的算法,在基本上不增加运算量的前提下,可以大幅度减少空间占用量,从而使复杂的计算可以在一般的计算机上实现。
The aim of this paper is to present an efficient method for solving a kind of large scale linear system with block-tridiagonal matrix. The method can save vast memory units without any appended operational expenses. So it is possible to do such a complicated operation in a common computer.
