Scale vector x in rescaled space back to original space
inverseRescale(x, cobra)a vector in the rescaled input space (usually \([-1,1]^d\))
list from cobraInit, we need here
a vector with lower bounds in original input space
a vector with upper bounds in original input space
a number, the rescaled lower bound for all dimensions
a number, the rescaled upper bound for all dimensions
z, inverse rescaling of vector x
