Class Description

Derivator()
*
Construct using a ROOT::Math::IGenFunction interface
explicit Derivator(const IGenFunction &f)
*
Construct using a GSL function pointer type
@param f :  free function pointer of the GSL required type
@param p :  pointer to the object carrying the function state
(for example the function object itself)
explicit Derivator(const GSLFuncPointer &f, void * p = 0)
virtual ~Derivator()
