摘要
分块矩阵是矩阵运算中一个很方便的工具,为了更好的利用此工具,本文将矩阵的初等变换、初等矩阵等概念推广到分块矩阵,得到分块初等变换、分块初等矩阵的概念,并举例说明了分块初等变换在分块矩阵行列式计算和分块矩阵求逆的方便之处.
Hyper matrix is a convenience tool in operation of matrix.For use this tool better,the conceptions of matrix elementary transformation and elementary matrix were spreaded to hyper matrix,then the conceptions of elementary transformation of hyper matrix and block elementary matrix were obtained.By illustrating with examples,the elementary transformation of hyper matrix is very convenient.
