Showing in Inverting Matrices (Linear Algebra)

MathAn elementary matrix is one that can be reached from the identity matrix I by a single elementary row operation, like row addition or row switching. Therefore `A = ((0,0,1),(0,3,0),(1,0,2)) =...

MathThe matrix `U` is the product of some particular set of elementary matrices. An elementary matrix can be reached from the identity matrix of the same dimension by an elementary row or column...
