Abstract
En 中文
In this paper, a two-parameter magnitude method (T-Mag) is proposed for solving real preconditioned interval systems of linear equations. By introducing two parameters, the proposed method generalizes the magnitude (Mag) method by Hlad & iacute;k (SIAM J. Numer. Anal. 52, 194-206, 2014) and produces a tighter enclosure. We establish the theoretical foundation and rigorously prove the key properties of the proposed method. Finally, some numerical examples are employed to verify the effectiveness of the proposed method.
