大型实对称矩阵特征值的数值解法

Methods of Computing the Eigenvalues of Large Real and Symmetric Matrix

本文介绍计算稀疏大型实对称矩阵特征值的方法—Davidson方法。并把它与矩阵的拟上三角化方法结合起来 。

In this paper ,Davidson Method, a method of computing the eigenvalues of large?sparse and symmetric matrix is introduced .Combined with the method of quasi-tridiagonalizing this method can be used to compute the eigenvalues of large?real and symmetric matrix.
