diagonally dominant

基本解释

Generalized strictly diagonally dominant matrices play an important role in many fields, but it isn't easy to determine a matrix is a generalized strictly diagonally matrix or not.
广义严格对角占优矩阵在许多领域中具有重要作用，但其判定是不容易的。
By means of the associated digraph of matrices we obtain the necessary and sufficient conditions of whether irreducibly doubly diagonally dominant matrices belongs to non-singular M-matrices.
借助于矩阵的伴随有向图得到了不可约双对角占优矩阵是否为非奇异M-矩阵的充分必要条件。
This article introduces the concept of local diagonally dominant matrics, studies the properties and eigenvalues of the matrics and offers its application in stability theory.
引进了弱局部对角占优阵的概念，研究这类矩阵的性质及其特征值问题，并给出了在稳定性理论中的应用。
