Test functions for global optimization posed for the SIAM 100-digit challenge in 2002 by Nick Trefethen, Oxford University, UK.

1 2 | ```
fnTrefethen(p2)
fnWagon(p3)
``` |

`p2` |
Numerical vector of length 2. |

`p3` |
Numerical vector of length 3. |

These are highly nonlinear and oscillating functions in two and three dimensions with thousands of local mimima inside the unit square resp. cube (i.e., [-1, 1] x [-1, 1] or [-1, 1] x [-1, 1] x [-1, 1]).

Function value is a single real number.
