摘要
本文对R^n上的一类奇异的非线性算子方程,给出了列修正拟牛顿法的收敛充分条件及其敛速估计.
Abstract For a class of nonlinear equation F(x)=0, in Rn, with the Jacobian F' being singular at the root x*,Column - update quasi Newton method is shown to yield a sequence that converges linearly to x* if the initial guess is chosen a special region.
