你要懂英文,自然知道该采纳我的.
Matrix decomposition has played a key role in the development of matrix theory and modern computing mathematics.
20世纪（几十?假设是70年代吧） In the late 70s of 20th century,the matrix QR decomposition jointly developed by Givens and Householder has been a fundamental part of it,it's of great importance in the solution of Numerical Algebra and optimization problem.
In this paper,the matrix QR decomposition methods and improvements,in addition to the applications based on the matrix QR decomposition theory have been approached and explored.
