Let A be a 10 × 10 matrix with cond∞(A) = 5×106.Suppose that the solution of a system Ax = b is computedin 15-digit decimal arithmetic and the relativeresidual, ||r||∞/||b||∞, turns out to be approximatelytwice the machine epsilon. How many digits of accuracywould you expect to have in your computedsolution? Explain.
