(1) Let a = (2.6, 4.7)T. Consider the floating-point algorithm with 3 digit rounding.
a) Compute fl(aTa).
b) Compute fl(aat).
c) Compute the Householder matrix Q generated by a as a 2x2 array. (Remember to round each computation to 3 digit)
d) Compute QTQ and ||QTQ - I||, here ||·|| is the matrix norm induced by the vector 1-norm.
