TY - JOUR TI - The numerical stability of a Laguerre-like method for the simultaneous inclusion of polynomial zeros AU - Petković Miodrag S. AU - Milošević Dušan M. JN - Publikacije Elektrotehnickog fakulteta - serija: matematika PY - 2006 IS - 17 SP - 93 EP - 109 PT- Article AB- The numerical stability of the fourth order iterative method of Laguerre's type for the simultaneous inclusion of polynomial zeros is analyzed in the presence of rounding errors. We state conditions under which the convergence order of the considered method is preserved. If these conditions are relaxed the convergence rate reduces to three.
