基于Thiele连分式逼近,建立了一个求解非线性方程的迭代公式.在一定条件下,证明了该迭代公式收敛阶数至少为四阶.实例证明该迭代格式是有效的且优于Newton迭代格式.
By means of Thiele's continued fraction, an iterative formula was presented and its convergent order was found to be at least four. Numerical examples verified that the iteration scheme is effective and superior to the Newton's scheme.
