gamma_distribution Class
Generates a gamma distribution.
template<class RealType = double>
class gamma_distribution {
public:
typedef T1 input_type;
typedef RealType result_type;
struct param_type;
explicit gamma_distribution(result_type alpha0 = result_type(1.0),
result_type beta0 = result_type(1.0));
explicit gamma_distribution(const param_type& par0);
result_type alpha() const;
result_type beta() const;
param_type param() const;
void param(const param_type& par0);
result_type min() const;
result_type max() const;
void reset();
template<class Engine>
result_type operator()(Engine& eng);
template<class Engine>
result_type operator()(Engine& eng,
const param_type& par0);
private:
result_type stored_alpha; // exposition only
result_type stored_beta; // exposition only
};
Parameters
- RealType
The floating-point engine value type.
Remarks
The template class describes a distribution that produces values of a user-specified floating-point type with a gamma distribution.
