nsider the following equations: 6X1 + 8x2 - 4x3 = 4 -8x1 + 18 - 9x3 = 16 - 1x1 - 1.5x2 + 3.5x3 = 5 (a) Write a Matlab code to solve the system (Find A and b. Leave x alone). (b) Write the output of the following programs using the A matrix found in (a): • A(:,1:2)' = [] (c) Match the following statements (1,2,3, and 4) with the (a), (b), (c), and (d) in the figure on the left: 1. Accurate, but Not Precise 2. Both Accurate and Precise (a) (b) 3. Precise, but Not Accurate 4. Neither Accurate nor Precise (c) (d) (d) True or False? If False, correct the statement to make it True. A = [1 a b; 0 1 d; 0 0 1] is an L triangular matrix from LU factorization.
