AbstrcatH-matrix is a class of widely used matrix.It is first presented that a characterization of an H-matrix by the splitting of matrix;then a more accurate bounds estimation for the inverse of an H-matrix is presented;finally the conclusions to a class of real matrix is extended.The method used in this paper is different from the others.Some recent results are imprived.
