Criteria for Generalized Nekrasov Matrices
Jianzhou Liu · Gongcheng shuxue xuebao · 2009
For any given matrix,we propose a practical sufficient criterion for generalized Nekrasov matrix by using just the elements of matrix,which is completed through the construction of a special positive diagonal matrix by definition and some techniques in the amplification and minification of inequality. Some numerical examples illustrate the effectiveness of our results.
