diagonally dominant造句

Notes on an equivalence condition of the generalized diagonally dominant matrices and the generalized subdiagonally dominant matrices;

In this paper, several criteria for generalized strictly diagonally dominant matrices are obtained and some existed results are improved by using the property ofα- diagonally dominant matrices, then a numerical example was given to illustrate the effectiveness of the results.

Some necessary and sufficient conditions for generalized strictly diagonally dominant matrices are given, and the corresponding results are improved.

In this paper, we give the estimates for the upper and lower bounds on the inverse elements of strictly diagonally dominant periodic tridiagonal matrices, and improve the latest findings.
