特征矩阵的右下三角等价形式
Right Lower Triangular Equivalent Form of Eigenmatrix
【摘要】 引入了n阶实矩阵的特征矩阵的右下三角等价形式,给出了仅用行初等变换化特征矩阵为右下三角等价形式的计算方法,并证明了它的计算复杂度为n3且有较好的内在并行性.值得指出的是右下三角等价形式有助于求解任意大型、超大型矩阵特征问题的并行算法研究.
【Abstract】 In this paper,the right lower triangular equivalent form of a real eigenmatrix of order n is defined.A calculation method using elementary row transformations to change the eigenmatrix to its right lower triangular equivalent form is given.The computational complexity is proved to be cubic n,and there is a better intrinsic parallism.The right lower triangular equivalent form is useful in the research of parallel algorithm to solve the eigenvalue problems of arbitrary large scale and super scale matrices.
