Abstract: |
A new algorithm is given to compute the transition matrix to transform the defective matrix into Jordan canonical form. The basic information that are easily obtained, such as the eigenvalues and their algebraic multiplicities, are used to generalize matrices, where their nontrivial column vectors are eigenvectors or generalized eigenvectors. They constitute a block matrix, from which all information of Jordan canonical form can be obtained by means of column elementary transformations. |
