Find A -1 as in Exercise 17, using A from Exercise 3. Data from in Exercise 17

Question:

Find A^-1 as in Exercise 17, using A from Exercise 3.

Data from in Exercise 17

When A is invertible, MATLAB finds A^-1 by factoring A = LU (where I may be permuted lower triangular), inverting L and U, and then computing U^-¹L^-¹. Use this method to compute the inverse of A.

Data from in Exercise 3

Solve the equation Ax = b by using the LU factorization given for A.
