4. MATLAB: Enter the following matrix and vector into Matlab: 2 9 7 9 21 57 1 6 1 8 0 3 3 9 1 3 8 0 6 5 0 4 18 6 7 5 3 0 9 0 1 6 7 2 6 2 1 7 3 14 15 926 6 6 2 6 0 6 9 3 1 2 7 1 8 28 18 1 To solve the linear system corresponding to the augmented matrix 1416) - 2 9 9 7 9 2 4 5 30 1 6 1 8 0 3 3 9 -6 138065 04 33 8 6 7 5 3 0 9 0 14 1 6 7 2 6 21738 3 14 15 9 2 6 26 6 6 2 6 0 6 9 3 -13 27 1828 18-11 (which also corresponds to the linear system in matrix-vector form, Ar = b), we may use the Matlab "backslash" command: Use this command to solve for the values 11,...,18. After solving for the vector 2, you can have Matlab check the answer by entering - Ay and seeing whether the result is all zero. Note: the numbers may not be identically "0", but they may be very small (6.g. of magnitude around 10-"). This is due to how mumbers are stored on the computer Now try to use the same approach to have Matlab solve the following linear system: -3x2 +2.13 = 8 -71 +212 - 13 = -2 -11-13 +3 = 6. and in a sentence, try to explain why A solution to this problem is -2, Matlab could not solve this
