Abstract: Some iterative criteriawith parameters for H-matrices are given according to the relations of α-diagonally dominant matrices and nonsingular H-matrices,which extend and improve some recent results.Effectiveness of the criteria is illustrated by some numerical examples.

Key words: nonsingular H-matrix, α-diagonally dominant matrix, irreducible, nonzero elements chain
