Gauss–Jordan elimination is a procedure for converting a matrix to reduced row echelon form using elementary row operations. It is a refinement of Gaussian elimination. The reduced row echelon form of a matrix is unique, but the steps of the procedure are not. Two linear systems are equivalent...
这里先给出一些铺垫:既然求逆,前提肯定是方阵A是可逆的,对矩阵A进行几种初等变换可以得到上三角矩阵U,假设分别经过了3种初等变换E,F,G最后得到U,那么A=GFEU,同时A总可以分解为一个下三角矩阵与一个上三角矩阵相乘,即A=LU,其中L为下三角矩阵,因此L=GFE。 当将A和E放在一起组成一个新的矩阵时,将A变化为...
In this chapter, we shall describe the Gauss鈥揓ordan elimination and show how the matrices associated with the various stages of the elimination process are utilized to expressin a factored form which is called theof(PFI). If at each stage in the Gaussian elimination not only the nonzero ...
