Detailed Description

template<class Scalar>
class RVL::RVLVectorLogisticInverse< Scalar >

This FO implements the inverse of the vector version of the logistic function $f(x) = x (1 + s^2 x^2)^{-1/2} + m$ , where $s=2/(f_{\rm max} - f_{\rm min})$ and $m=(f_{\rm max} + f_{\rm min})/2$ .

The inverse is $f^{-1}(y) = (y-m) (1 - s^2(y-m)^2))^{-1/2}$ , well-defined when $f_{\rm min} < y < f_{\rm max}$ .
