Sažetak(ne postoji na srpskom) 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.
