WebComputes the vector x that approximately solves the equation a @ x = b. The equation may be under-, well-, or over-determined (i.e., the number of linearly independent rows of a can be less than, equal to, or greater than its number of linearly independent columns). WebA = A = Siga eriti 2. A = A = 2.5 EXERCISES vities In Exercises 1-6, solve the equation Ax = b by using the LU factorization given for A. In Exercises 1 and 2, also solve Ax = b by ordinary row reduction. $1 ei tuqni ar HER -3 5 42 obsl 100 -1 1 0 owl smid 2 -5 1 1 -1 3 -7 -2 1812151 1 own gat 6 -4 7130 2 2 3. WebTo solve Ax = b we can try to: 1)Find an LU factorization of A; then LUx = b: 2)Solve Ly = b with forward substitution. 3)Solve Ux = y with backward substitution. That is, we solve L(Ux) = b for Ux then solve for x from that. You already know how to do this from linear algebra - Gaussian elimination! 7/39 laws of information theory
