摘要
给出o-对称矩阵概念及结构,研究其中具有轴对称结构矩阵的Schur分解和正规阵分解与其一子阵Schur分解和正规阵分解之间的定量关系,得到一些新结果,据此可大大减少这类结构矩阵的Schur分解及正规阵分解的计算量和存储量.
The concept and structure of o-symmetric matrix are gaven.The quantitative correspondence of the Schur decomposition and normal matrices decomposition between its submatrix is studied,Some new results are obtained,based on this,the CPU time and memory are dramatically saved for Schur decomposition and normal matrices decomposition of this Class of structure matrix.
