M-矩阵与其逆矩阵的 q(A °A-1)的进一步研究
Further Research on the q(A °A-1)of an M-matrix and its Inverse
摘要
Abstract
The q(A°A-1 )of an M-matrix and its inverse is further researched by using the theorem for lo-calizations of matrix eigenvalues,and some new estimations are obtained.There are the theoretical analysis and numerical figure show that the new estimating formulas have improved the conjecture of Fiedle and Markham effectively and other existing results in some cases.关键词
