چکیده
|
We propose an approach to enhance the performance of a diagonal variant of secant method for solving large-scale systems of nonlinear equations. in this approach,we consider diagonal secant method using data from two preceding steps rather than a single step derived using weak secant equation to improve the updated approximate jacobian in diagonal form. the numerical results verify that the proposed approach is a clear enhancement in numerical performance. copyright © 2012 m. y. waziri et al.
