Solutions to Exercises for Section 6
... c = d. So there are 10 reducible monic polynomials of degree 2, leaving 6 monic irreducible polynomials of degree 2. To find one of these irreducible polynomials, you could compute the 10 reducible ones and then take a polynomial not on the list, but that looks a little tedious, so you could just ch ...

10 The Singular Value Decomposition
... equal to the transpose of V . Of course, this argument requires V to be full rank, so that the solution L to equation (69) is unique. However, V is certainly full rank, because it is made of orthonormal columns. Notice that V R = I cannot possibly have a solution when m > n, because the m × m identi ...

... that is, a rounding error in the (huge) u22 entry causes a complete loss of information about the a22 component. In this example, the l21 and u22 terms are both huge. Why does this matter? When L and U have huge entries and A does not, computing the product LU must inevitably involve huge cancellati ...
