On the processes of preorthogonalization of some vector families which appear while plotting characteristic polynomials of matrices and used while solving the system of linear algebraic equations

In accordance with published data some methods of indirect determination of characteristic matrix polynome based upon orthogonalization of some vectors sequences have been outlined in the paper. The normal course of calculation process is shown to be dependent not only on the structure of the initial matrix but also on appropriate choice of the initial vector (or a couple of vectors if a method of bioorthogonalization is the case in point). <<back
