The norm of the inverse is needed for the condition number of that matrix. The algorithm exploits the effect the Gauss—Jordan elimination is equivalent with writing the matrix as a product of n elementary matrices. These elementary matrices are sequentially used to maximize (locally) the norm ...
Gauss-Jordan :"solve two equations at once" steps: 1.write down the identify matrix(单位矩阵) on the right side of matix A to get the augmented matrix(增广矩阵). 2.eliminant the augmented matrix to be a matrix which consists an identify matrix and A inverse. Eliminant procedure is like...
Also called the Gauss-Jordan methodThis is a fun way to find the Inverse of a Matrix:Play around with the rows (adding, multiplying or swapping) until we make Matrix A into the Identity Matrix I And by ALSO doing the changes to an Identity Matrix it magically turns into the Inverse!
高斯-若尔当消元法(Gauss-Jordan Elimination) 高斯消元法,是线性代数中的一个算法,可用来求解线性方程组,并可以求出矩阵的秩,以及求出可逆方阵的逆矩阵。高斯消元法的原理是:若用初等行变换将增广矩阵 化为 ,则AX = B与CX = D是同解方程组。 所以我们可以用初等行变换把增广矩阵转换为行阶梯阵,然后回代...
高斯-若尔当消元法(Gauss-Jordan Elimination) 相对于高斯消元法,高斯-若尔当消元法最后的得到线性方程组更容易求解,它得到的是简化行列式。其转化后的增高矩阵形式如下,因此它可以直接求出方程的解,而无需使用替换算法。但是,此算法的效率较低。 例子如下: ...

R = rref(A) returns the reduced row echelon form of A using Gauss-Jordan elimination with partial pivoting. example R = rref(A,tol) specifies a pivot tolerance that the algorithm uses to determine negligible columns. [R,p] = rref(A) also returns the nonzero pivots p. exampleExamples...
