Matlab: I need a Matlab code for number 8d. Algorithm 6.1 is Gaussian Elimination with Backward Substitution, so I need a code for that. Thank you, in advance.

8. Use Algorithm 6.1 and single precision computer arithmetic to solve the following linear systems. computer arith 2.71x1+X2+1032x3= 12, 4.1 2x1-x2+ 500x3= 11.49. 3.33x 2x2 200x3 41 b. ++3-2. exi- x2+x+ 2x4-1, 2x1 + 2x2 + X3- x4 + x5 4, 3m + x2-3x3-2x4 + 3x5 = 8, 4x1 + x2-x+4x -5xs 16
