Hello everyone, i've been searching in this book forever to find an example but no luck. My problem states: Find two Elementary matrices E1 and E2 such that [tex]B = E_2E_1A[/tex] A = 2 3 -1 8 B = 1 11 3 -24 Can someone explain to me what they want me to do? The books says: A -> E1A->E2E1A -> Ek .... E2E1A; Ei denote the elementary matrix corresponding to the ith row operation. and suppose that a series of k elementary row operations is applied to an arbitrary matrix A. THanks!
