Public Member Functions
	LK_SigmoidalFunc ()
func::FuncOP	clone () const
virtual Real	func (Real const x) const
	a Sigmoidal function that ramps from 1 to 0 over a certain range. Thanks to Mike Tyka for having a sigmoidal function on the top of his head. More...
virtual Real	dfunc (Real const x) const
	Returns a value representing the derivative of this function evaluated at a given point. More...

virtual	~Func ()
	Automatically generated virtual destructor for class deriving directly from ReferenceCount. More...
virtual void	read_data (std::istream &)
	initialize this Func from the given std::istream. More...
virtual Real	estimate_dfunc (Real const r) const
	Estimates the derivative of this function at a given radius by calculating the slope of the secant line from func(r) and func(r+1e-05). More...
virtual Real	estimate_dfunc (Real const r, Real const h) const
	Estimates the derivative of this function at a given radius by calculating the slope of the secant line from func(r) and func(r+h). More...
virtual void	show (std::ostream &out) const
	Prints out space-delimited columns for r, func, dfunc and dfunc_est. The values for func, dfunc and dfunc_est are plotted as a function of r, which is varied from 2-20 in steps of 0.5. The value for dfunc_est is the estimated by the method estimate_dfunc( r ). More...
virtual void	show_definition (std::ostream &out) const
	shows the definition of this function, usually the string type of function and the parameters passed in to the constructor. More...
virtual Size	show_violations (std::ostream &out, Real r, Size verbose_level, Real threshold=1) const
	show some sort of stringified representation of the violations for this constraint. More...
