求解非线性方程组的改进不精确雅可比牛顿法
Modified incomplete Jacobian Newton method for nonlinear equations
摘要
Abstract
This paper presents a new modified Incomplete Jacobian Newton(IJN)method for nonlinear equations whose incomplete Jacobian matrix is singular in a neighborhood of exact solution. This method uses a part of elements of the Jacobian matrix and equations function to obtain the next iteration point without additional computational capacity. The numerical tests show that the modified IJN method has the same calculation efficiency with original IJN method, but more convenience and effective.关键词
