- Abstract:
- Drazin inverse of matrix A can be expressed by polynomial of A. In order to obtain a polynomial of less degree, the structure of Drazin inverse of matrix is analysed by using the theory of Jordan canonical matrix , and a computational method for polynomial d( K) of least degree is given by using coefficients of minimal polynomial of matrix such that d ( A) is Drazin inverse of A. It simplifies the computational method for Drazin inverse of matrix which we have known.
