| heal.abstract | In this paper it is assumed that the point (or block) Jacobi matrix J(k) associated with the matrix A is weakly k-cyclic consistently ordered with complex, in general, eigenvalue spectrum sigma(J(k)). It is then our objective to begin a study in order to extend the Young-Eidson algorithm for the determination of the real optimum relaxation factor in the monoparametric k-step iterative method or equivalently in the case of the Successive Overelaxation (SOR-k) method when sigma(J(k)) lies in a cusped hypocycloid region. In addition a number of concluding remarks are made and numerical examples are given, that support the theory developed in this paper. | en |
