Let Edenote a 50 × 50 elimination matrix where the entry in the ith row and ith column below the main diagonal is non-zero and all other off- diagonal elements are zero. For i = 5, j = 2 find the set of elimination matrices Eng where EpEi EiEpa. Using the action of an elimination matrix when it is applied on another matrix, can you explain why commuta- tivity works for some pairs of elimination matrices and not for others? Give adequate justifications. = Let Edenote a 50 × 50 elimination matrix where the entry in the ith row and ith column below the main diagonal is non-zero and all other off- diagonal elements are zero.
