Consider the Euclidean norm 1/2 n 3) = ||| i=1 computed using floating point arithmetic. (a) Explain how you would implement this sum to minimize roundoff error in the compu- tation. Give an example where the result is more accurate than the obvious implemen- tation. (b) Give an example where the obvious implementation can create an overflow and discuss how one could avoid this problem.
