摘要
本文研究了行(列)转置矩阵与行(列)反对称矩阵的性质.利用分块矩阵理论获得了许多新的结果,给出了行(列)反对称矩阵的满秩分解、秩分解和广义逆的公式及快速算法.它们可极大地减少行(列)反对称矩阵的满秩分解、秩分解和广义逆的计算量与存储量,并且不会丧失数值精度.
In this paper, we study the properties of row (column) transposed matrix and row (column) antisymmetric matrix. By using partitional matrices we acquire many new results. In addition, the formulas of the full rank factorization, rank factorization and generalized inverse of row (column) antisymmetric matrix are given, which make calculation easier and accurate.
