5. Consider the N x N tridiagonal matrix 2 +h2 and the vector f (f, f2, . . . , N) T , where fi 2ih+1, -2-n, M-2n-1 , -1, 2, . . . , 8. Take e 10-3 and solve the system Au - f using LU factorization for a tridiagonal matrix as discussed in class. In your code do not create the matrix A. For each value ofn -1, 2,... ,8, plot the points (ui, xi), i-1,..., N, where u is the solution of the system and xi-ih. -Tm 5.
