A HIGH-ORDER ITERATIVE FORMULA FOR SIMULTANEOUS DETERMINATION OF ZEROS OF A POLYNOMIAL

[摘要] We propose a hybrid method to determine all the zeros of a polynomial, simultaneously, by combining the single-root method and the simultaneous one. The present method has a high convergence order even for multiple roots by using the Pade approximation.
