An analysis of a Khattri's 4th order family of methods
MetadataShow full item record
In this paper we analyze an optimal fourth-order family of methods suggested by Khattri and Babajee, (2013). We analyze the family using the information on the extraneous fixed points. Two measures of closeness to the imaginary axis of the set of extraneous points are considered and applied to the members of the family to find its best performer. The results are compared to three best members of King's family of methods.

Neta, Beny; Chun, Changbum (Columbia International Publishing, 2015);In this paper we analyze an optimal eighth-order family of methods based on King's fourth order method to solve a nonlinear equation. This family of methods was developed by Thukral and Petković and uses a weight function. ...
Neta, Beny; Chun, Changbum; Kim, Sujin (World Scientific Publishing Company, 2014-07-29);P. Jarratt has developed a family of fourth-order optimal methods. He suggested two members of the family. The dynamics of one of those was discussed previously. Here we show that the family can be written using a weight ...
