A new proof of interval extension of the classic Ostrowski's method and its modified method for computing the enclosure solutions of nonlinear equations

摘要

In this paper we give a new proof for interval extension of the classic Ostrowski's method and its modified method for computing the root enclosures of nonlinear equations, which was introduced by Bakhtiari et al. (Ann. Univ. Ferrara, 59, 221-234, 2013).
