Detailed Description
This function is used to unit-test the case of expansion to infinity It returns infinity when x is in between -1 and 1.

◆ operator()()

We overload the operator as is required in GenericCostFunction to calculate the cost of the function.
Behaviour: cost = x if x > 1 and x < -1, infinity otherwise
Intended use : InfinityInBetween Func; cost = Func(const std::vector<double> x);
NOTE sicne this function actually retrns x, from th Nelder-Mead persepctive it behaves like a parabola, since NM squares the cost
Parameters:
- Parameters
-
x (input) vector containing coordinates of x (1D)
- Returns
- cost as a vector
Implements Unfit::GenericCostFunction.
