Unformatted text preview: all steps to your calculations. Problem 3: LU-decomposition using Gauss multipliers: Find L and U for matrix A by performing a Gauss elimination and using the multipliers to find the lower triangular matrix. A= 2 -3 2 -6 10 -3 -4 7 -2 Do not use Matlab lu function.( see example 6.4 in book page 287) Problem 4: Direct calculation of L and U: Solve book problem 4 page 290. Do not use Matlab lu function. Problem 5: Condition number: Solve book problem 20 page 301. Use Matlab inv function to invert the matrix. Do not use MATLAB predefined function cond and norm. Problem 6: Ill-conditionning : Solve book problem 24 page 301 ( ICS1 and ICS2 are defined p. 298, do part a, b and c). Which one of the diagnostic inspections most strongly suggests ill-conditioning? You may use all of Matlabs predefined functions to find the solution to this exercise....
