3. Rational extrapolation

Let (S n ) be a sequence of numbers, vectors or matrices that converges to S. When its convergence is slow, we transform it, without modifying it, into a new sequence (T n ) which, under certain assumptions, converges faster to the same limit, i.e. such that

Such methods are called sequence transformations or convergence acceleration and...
