GeomLib_PolyFunc (const math_Vector &Coeffs)  
virtual Standard_Boolean  Value (const Standard_Real X, Standard_Real &F) override 
computes the value <F>of the function for the variable <X>. Returns True if the calculation were successfully done, False otherwise.  
virtual Standard_Boolean  Derivative (const Standard_Real X, Standard_Real &D) override 
computes the derivative <D> of the function for the variable <X>. Returns True if the calculation were successfully done, False otherwise.  
virtual Standard_Boolean  Values (const Standard_Real X, Standard_Real &F, Standard_Real &D) override 
computes the value <F> and the derivative <D> of the function for the variable <X>. Returns True if the calculation were successfully done, False otherwise.

virtual Standard_Integer  GetStateNumber () 
returns the state of the function corresponding to the latest call of any methods associated with the function. This function is called by each of the algorithms described later which defined the function Integer Algorithm::StateNumber(). The algorithm has the responsibility to call this function when it has found a solution (i.e. a root or a minimum) and has to maintain the association between the solution found and this StateNumber. Byu default, this method returns 0 (which means for the algorithm: no state has been saved). It is the responsibility of the programmer to decide if he needs to save the current state of the function and to return an Integer that allows retrieval of the state.
