摘要
矩阵的初等变换及矩阵的分块是矩阵论中在理论及计算上的两个重要方法。本文将初等变换推广到分块矩阵上去,并在引进了准初等变换这一概念后,证明了它的某些性质。本文的目的在于简化某些矩阵运算,并希望这一新建立的概念和结论得到更广泛的应用。
The elementary transformation and partitioning of matrix are two important methods applied in both theory and calculation. This article extrapotates the elementary transformation to partitioning matrices and proves some properties after introduction of the notion catted as pre-ele-mentary transformations. The Purpose of this articte is to simptify some of the operations on matrices.
