【 摘 要 】

Based on the argument principle, we propose an adaptive multilevel subdivision algorithm for the computation of all the zeros of an analytic function f : C --> C within a bounded domain. We illustrate the reliability of this method by several numerical examples. (C) 2002 Elsevier Science B.V. All rights reserved.
