摘要
本文讨论利用仿正交变换于分块矩阵（Ａ，Ｅ），当左边实满秩方阵Ａ化为正线上三角阵Ｒ时，右边的单位矩阵Ｅ可同时化为正交矩阵，从而实现对矩阵Ａ的ＱＲ分解．
The main purpose of this paper is to discuss using sub-orthogonal row transfor mation in block matrix (A,E), when its real nonsingular matrix A is transformed into up-triangular matrix R of diagonal elements which are positive. Meanwhile, unit matrix E will be transformed into orthogonal matrix. Therefore, the QR decompositions of matrix A will be realized.
