摘要: 本文利用分式线性函数在x0处近似f(x)而导出一种求方程f(x)=0的根的迭代公式,它的变形包括Hally方法,在一定的条件下证明了二阶收敛性。Abstract: Using fractional linear function (also called pseudolinear function) to approximate a function f (x) at a specific point Xo, a iteration scheme for the solution of equation f (x)=0 is developed the variant of the method includes the well-known Hally method. Under the appropriate condition the quadratie convergence is proved.
