1. Two m X n matrices are said to be row equivalent if one can be obtained from the other by a sequence of elementary row operations. Equivalently, two matrices with the same rref are row equivalent. Use the MATLAB command rref(A) to determine which of the following matrices are row equivalent to A = 2 5 6 7 9 10 11 1 1 1 (a) 1 0 -1 -2 0 1 2 3 1 3 (b) 5 6 9 4 8 12 2 4 7 8 10 11 12
