【摘要】 本文得到了块对角占优矩阵奇异与非奇异的几个充分必要条件,并由此得到了广义块对角占优矩阵奇异与非奇异的一些充分必要的判定条件。

【Abstract】 Necessary and sufficient conditions for a matrix to be singular/nonsingular are obtained under the assumption that the matrix is a block diagonally dominant (BDD) matrix. For a generalized block diagonally dominant (GBDD) matrix, necessary and sufficient conditions are obtained based on the results for BDD matrices.
