WebbRichardson Extrapolation is an idea which can often be used to improve the results of a numerical method: from a method of order O(h p) it gives us a method of order O(h p+1).. Suppose you want to approximate a quantity Q, and you have available approximations Q(h) for h > 0. Typically, you know that this approximation is of a certain order, say
