Detailed Description

template<class Type>
class FunctorBase< Type >

Abstract templated explicit functor class.

This class represents an explicit functor. Actual non-abstract functor is obtained by deriving from this class and overriding the operator(). Parameters can be set and used by the methods of ancestor class FunctorCommon.

The template is used to enable computing derivates by FADBAD++ library. The virtual operator() needs to operate both with type double and FADBAD++ types, such as B<double> and T<double>.

Simple usage example for function $x^3p_1+\frac{p_2}{p_3}$ with three parameters:

template<class Type=double>
class Cubic : public FunctorBase<Type>
{
public:
  typedef enum{ p1, p2, p3
  } Parameters;
  
  Cubic(double pp1, double pp2, double pp3)
  {
    this->set_param(p1, pp1);
    this->set_param(p2, pp2);
    this->set_param(p3, pp3);
  }
  
  Type operator()(Type x)
  {
    return x*x*x * this->param(p1) + this->param(p2)/this->param(p3);
  }    
};
