Abstract: | By using a continuous transition method of a matrix and the estimate for spectral radius of a sub-matrix etc.,decision methods for a generalized H-matrix under positive definite matrix conditions are researched.Some new sufficient conditions for generalized H-matrices are obtained.When a block matrix degenerates a point matrix, these conditions namely become sufficient conditions of H-matrix. |
