对n元非线性方程组f(x)=0的求解,二步割线法是一种有效的算法,本文证明,它的"根收敛阶"不小于方程t~(n+1)-t~n+2=0的唯一正根.
The two-step secant method is an efficient algorithm for solving nonlinear equations with n variables. We prove in this paper that the rootconvergence order of this method is not less than the unique positive root of equation t~(n+1)-t~n-2=0.
