FixedPoint

For functions that take and return vectors (or scalars), this package provides 8 algorithms for finding fixed point vectors (vectors for which the inputs and outputs to the function are the same vector). These algorithms include Anderson (1965) acceleration doi:10.1145/321296.321305, epsilon extrapolation methods (Wynn 1962 doi:10.2307/2004051) and minimal polynomial methods (Cabay and Jackson 1976 doi:10.1137/0713060).
