Abstract:
Applying the theorem of diagonally dominant matrix, the criteria of interval H-matrix is discussed. Some sufficient conditions for interval H-matrix are given, we obtain some criteria of regular interval H- matrix. These results can imlJrove and generalize criteria of interval H-matrix.[著者文摘]
Key words:
Interval H-matrix; Interval regular matrix; Interval a-diagonally dominant matrix
