New algorithm for polynomial spectral factorization with quadratic convergence. I
In this paper, we present a family of three-point with eight-order convergence methods for finding the simple roots of nonlinear equations by suitable approximations and weight function based on Maheshwari’s method. Per iteration this method requires three evaluations of the function and one evaluation of its first derivative. These class of methods have the efficiency index equal to [...] 814≈1.682. We describe the analysis of the proposed methods along with numerical experiments including comparison...
