摘要
通过矩阵分块的方法,探讨了五对角逆M-矩阵的结构,给出了五对角逆M-矩阵的充分条件,进一步证明了这类五对角矩阵在Hadamard积下的封闭性。
By the partitioning of block matrices, the structure of Five-diagonal inverse M- Matrices is discussed and a sufficient condition of five-diagonal inverse M- matrices is also put forward. It further proves its sealing properties under Hadamard product.
