工程中的计算问题大部分都可转化成求解线性方程组的问题，而这些线性方程组有的时候是不相容的，本文研究以一些特殊的长方矩阵为系数阵的不相容方程组——Vandermonde方程组，Toeplitz方程组，Loewner方程组等的极小范数最小二乘解的快速算法，以及求这些特殊矩阵的左逆及右逆的快速算法。
Taking asphalt anticorrosive coating as an example,by using the theory of an Markov chain,the application of an inverse matrix in prediction for coating degradation was illustrated,which provides a basis for determining the aging distribution of the pipeline s external anticorrosive coating.
介绍了埋地燃气管道外防腐层老化状况评价标准,以沥青外防腐层为例,通过应用马尔可夫链理论,阐述了基于逆阵的外防腐层老化状况预测的方法,从而为确定整条管线外防腐层老化状况分布提供了理论依据。
Inverse matrix is an important matrix in linear algebra ,whether can use line or list transformation simultaneously in obtaining the inverse matrix of a given matrix? This paper deals with the problem.
逆阵是线性代数中的一个重要矩阵,能否同时使用矩阵的初等行、列变换求逆阵?本文就这一问题进行探讨。
