Generalized alpha-diagonal dominance
In order to achieve further investigation, new extended concepts of so-called a-generalized diagonal dominance are introduced. These extended diagonal dominant matrices introduced are all subclasses of nonsingular H-matrices, and extended practical sufficient conditions of nonsingular H-matrices and nonsingular M-matrices are presented.
