We construct a new general class of derivative free n-point iterative methods of optimal order of convergence 2 (n-1) using rational interpolant. The special cases of this class are obtained. These ...

Abstract: Two main ideas are introduced: (1) the use of model-based parameter estimation based on rational function approximations, which reduces the number of frequencies at which solutions or ...

Abstract: Any order analog fractance circuit based on a method of constructing the rational approximation function in the form of factorization is designed. The circuit is made up of level-N passive ...
