Computation of Jordan Canonical Form and Transition Matrix by Block Matrix Formed with Jordan Chains
【摘要】 复数域上亏损矩阵的广义特征子空间的基的每个向量生成若当链,构成分块矩阵,施以初等变换,可求出若当基.获得若当标准形与相似变换矩阵的新算法.
【Abstract】 By elementary transformations,a Jordan basis is got with a block matrix which is formed by the Jordan chains generated by every vector in a basis of the generalized eigensubspace of a defective matrix in complex field.A new arithmetic is given to compute the Jordan canonical form and transition matrix.
