A Note on Estimation for the Spread and the Rank of Matrices
摘要
Abstract
First of all, we build a new matrix based on the original matrix, some new estimations for the spread and the rank of matrices is obtained in this paper through finding upper bound by estimating upper bound value for the sum of squares of the module of eigenvalues of the original matrices, and at last, some numerical examples verify the effectiveness of our results.关键词
