Polynom approximation
WebThe approximation thus achieved is “almost best.” Implementing the algorithm to some practical problems is described. Since a solution to a linear systemAx=b isx=A −1 b, an iterative solution algorithm can be based upon a polynomial approximation tof (A)=A −1. We give special attention to this important problem.
