Problem 45948. Function minimization - beat fminbnd!

Matlab's fminbnd function finds a minimizer of a function within an interval. If often gets stuck in local minima.

Can you do better than fminbnd, for a single variable?

You are given a function handler fun (one scalar input, one scalar output) and a the search bounds xmin and xmax. Return a minimizer xopt between xmin and xmax such that fun(xopt) < fminbnd(fun,xmin,xmax)

Check Problem 45951 for the unbounded version (harder)!
