On bounding zeros of analytic functions

An algorithm CZ for bounding simple and multiple zeros z* ∈ D ⊆ C of an analytic function f : D ⊆ C → C in a compact set z ⊂ D where D ⊆ Cis an open convex set is given. The algorithm is easy to implement using, for example Fortran 95. Some numerical results are presented.
