3. Create the matrices 1 2-3 45 B1 2 -279 1

3. Create the matrices 1 2-3 45 B1 2 -279 1 10 6 12 2 4 -6 8 11 A- 13 5 2 1-1 using Matlab and repeat the following for both A and B (a) Form the super augmented matrix using a command similar to super-[A eye (3)1 (b) Use Gusian elimination (e-g, using rret) to determine the inverse of A (and B). (c) Verify that the inverses calculated in Part (b) are indeed the inverses of A and B using (i) the inv command and (i) checking that AAI and BB-1I . Enter the matrix ones (4) in Matlab. How many linearly independent columns does this matrix have? Why can we say immediately that this matrix is not invertible
