Some Inequalities on Hadamard Product of M- matrix
LI Yan-ya · Journal of Yanan University · 2013
Using the estimations of the lower bound of elements of inverse matrix of nonsingular M- matrix,give the new estimators of lower bound of minimum eigenvalue for the Hadamard product of A and A-1. These estimates depend only on the matrix elements,and are the best than the prior estimation precision under certain conditions.
