spin-Peierls强关联系统中的Lanczos方法

Lanczos Method in Spin-Peierls System

在处理问题时,我们常常利用Lanczos方法进行数值计算,那么Lanczos方法到底具有什么优点呢?文章主要通过 Lanczos和Householder这两种方法的比较,说明了Lanczos数值计算方法的优越性。

In setting a question, we often calculate things by Lanczos numerical method, what merit on earth has lanczos method？ It is demonstrated that Lanczos method is superior to Householder method in solving a question by comparison in this paper.
