幂法求矩阵特征值的一些补充

Some Supplements for the Power Method to Evaluate Matrix Eigenvalues

给出一个幂法求矩阵特征值的改进方案，在通常幂法失效时。

In this paper,we present a scheme for the power method to evaluate matrix eigenvalues.Fail in the usual power method,obtain largest eigenvalue in absolute value and other eigenvalues of the matrix.
