摘要
给出o-对称矩阵概念及结构,研究其中一类o-对称矩阵的LDU分解和Cholesky分解及三对角分解,给出了分解公式,得到一些新结果,据此可大大减少这类矩阵的LDU分解和Cholesky分解及三对角分解的计算量和存储量.
This paper gives concept and structure of decomposition and triple diagonal decomposition of a formula, and obtains some new conclusions, which can o-symmetry matrix, studies LDU decomposition, Cholesky class of o-symmetry matrix, proposes its decomposition largely reduce the calculation and storage quantity of the three kinds of decompositions of this class of matrix.
