求一类方程重根的广义Newton迭代法
An generalized Newton iterative method for extracting the roots of a category equation
【摘要】 设方程f(x)=0有λ重根,其中λ为任意正实数,函数f(x)可能不可导,给出了求这一类方程的λ重根的一个广义Newton迭代法,并证明了这种方法的收敛阶为2.
【Abstract】 In order to get the λ repeated roots of equation f(x) = 0, where λ∈R~+ and the equation may be underivative, an generalized Newton iterative method was constructed with order 2 as its convergence. It is an improved general Newton method.
