摘要
提出了2种构造多项式,通过求该多项式的根,获得矩阵部分特征值的方法,数值算例比较了这2种方法,表明了这2种方法对于求解较小规模矩阵特征值的有效性和准确性.
Two methods to construct a polynomial are first introduced,and then the roots of the polynomial are calculated in order to obtain some of the eigenvalues.These two methods are compared by numerical experiments which show that the methods are effective and accurate to solve the eigenvalues of smaller matrix.
