matlab program
Write computer code that solves systems of linear equations using LU decomposition (you to pick Crout or Doolittle) without pivoting, and performs iterative refinement, Iterate unt maximum approximate error is below 0.001%. Use your code to solve the same system as 1, shown again below: -2X1 + 1x2-9Xs + 2x4 + 2x5-5x6 + 1X1 + 8x8-1x9= 6 1X1-6x2+ 3x3 + 12x4 + 1 1Xs-3x6-7x7+ 2x8-2x9 = 10 2X1-3x2-1x3 + 2x4 + 5xs+ 13xs+ 2x7 + 16x8 + 3x9 = 25 -6X1 + 2X2-3Xs + 1X4 + 2xs-1Xs + 14x, + 2x8-2x9 =-12 -1X1-13x2+ 4x3-4x4 + 3Xs + 7Xs-3x7+2x8-3x9 = 18 15x1 + 3x2-5x3 + 7x4-2Xs + 5xs+ 2x7+ 1Xs-1Xs = 23 14X1 + 3X2-5Xs + 7Xa-2Xs + 5Xs + 2x, + 1x8-1x9 = 24 3x1 + 2x2 + 2x3-5x4-2x5-14x6 + 6x7+7Xs-2Xs=8 3x1 + 2X2 + 3x3 _ 4x4-2Xs-13x6 + 6x7 + 7x8-2x9 = 9
