Iterative Methods for An Inverse Problem Year: 2011 Volume: 5 Issue: 4 649 - 651 Pages Authors: Minghui Wang Shanrui Hu Abstract: An inverse problem of doubly center matrices is discussed. By translating the constrained problem into unconstrained problem, two iterative methods are proposed. A numerical example illustrate our algorithms. Keywords: doubly center matrix electric network theory iterative methods least-square problem.
