Question:
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 in Exercise 2.
Data from in Exercise 2
Solve the equation Ax = b by using the LU factorization given for A. Also solve Ax = b by ordinary row reduction.
