摘要
本文给出了Lanczos算法的判据的一种计算方法,将其与Lanczos算法中出现的三对角方程组的解相联系,提出了一种Lanczos方法。附有数值算例。
In this paper, a computing method for the criterion of the Lanczos Algorithm is present-ed. By associating it with the solution of the tridiagonal equations which appears in the Lanc-zos Algorithm, a kind of Lanczos Algorithm is presented. Some numerical experiments areattached.
