方阵A的LU分解的初等行变换法

AN ELEMENTARY ROWTRANSFORMATION METHOD OFCALCULATING LUFACTORIZATION

利用矩阵的初等行变换得到求方阵的ＬＵ分解的一种新方法，它与通常用的方法相比较可节省一半的计算量，对于求解线性方程组具有一定的实际意义．

Ufactorization is very important for calculating linear equations. In our paper, using elementary rowtransformation, we′ve obtained a new method of calculating LUfactorization of a matrix A. Comparied with the usual method, half of computing amount is saved.
