Create three row vectors:
a = [3 -1 5 11 -4 2]
b = [7 -9 2 13 1 -2]
c = [-2 4 -7 8 0 9]
(a) Use the three vectors in a MATLAB command to create a 3 × 4 matrix such that the first, second, and third rows consist of the last four elements of the vectors a, b, and c, respectively.
(b) Use the three vectors in a MATLAB command to create a 3 × 3 matrix such that the first, second, and third columns consist of the first three elements of the vectors a, b, and c, respectively.
