【摘要】 达尼列夫斯基(Danileusky)法是求方阵特征多项式的一个有效方法。这种方法实质上是对n阶方阵A作(n—1)次相似变换,其结果是把方阵A变成相伴矩阵P,从而得到A的特征多项式。本文仅对达氏方法作些改进,使结构更加简洁,同时也论证了这种方法的可行性。更多还原

【Abstract】 As we know, Danilevsky method is an effective and ingeniousmethod. This method essentially performs (n-1) similarity transformation on thesquare matrix A of order n, with the result that matrix A becomes companionmatrix P. This paper improves the method with the structure simplify and themethod has been also proved.更多还原
