Explanation An elementary matrix is any matrix that can be obtained by performing an elementary row operation on an identity matrix. Given, C = [ 1 2 − 1 1 1 1 2 1 − 1 ] , D = [ 1 2 − 1 − 3 − 1 3 2 1 − 1 ] Here identity matrix I 3 will be I 3 = [ 1 0 0 0 1 0 0 0 1 ] In order to determine elementary matrix E such that ED = C, we need to obtain C by performing elementary row operation on D
