Extrema_GenLocateExtPS::Extrema_GenLocateExtPS ( const gp_Pnt P,
const Adaptor3d_Surface S,
const Standard_Real  U0,
const Standard_Real  V0,
const Standard_Real  TolU,
const Standard_Real  TolV 
)

Calculates the distance with a close point. The close point is defined by the parameter values U0 and V0. The function F(u,v)=distance(S(u,v),p) has an extremun when gradient(F)=0. The algorithm searchs a zero near the close point.
