一种改进的逆Broyden算法

A Revised Quasi-Broyden Algorithm

对解非线性方程组Broyden方法和逆Broyden方法进行了改进,构造了求解非线性方程组F(x)=0的一个迭代公式,并讨论了其收敛性,说明该算法是有效的.

We improved Broyden and Quasi-Broyden methods of solving nonlinear equations and constructed a new iterative method for solving nonlinear equations F（ x） = 0 in this paper. The convergence is presented and the result is given to illustrate the efficiency of this method.
