boost::gamma_distribution

## Synopsis

    // In header: <boost/random/gamma_distribution.hpp>

    template<typename RealType = double>
    class gamma_distribution {
    public:
      // types
      typedef RealType input_type;
      typedef RealType result_type;

      // construct/copy/destruct
      gamma_distribution(const result_type & = result_type(1));

      // public member functions
      RealType alpha() const;
      void reset() ;
      template<typename Engine> result_type operator()(Engine &) ;
    };

## Description

The gamma distribution is a continuous distribution with a single parameter alpha.

It has .

### `gamma_distribution` public construct/copy/destruct

1.     gamma_distribution(const result_type & alpha_arg = result_type(1));

### `gamma_distribution` public member functions

1.     RealType alpha() const;

2.     void reset() ;

3.     template<typename Engine> result_type operator()(Engine & eng) ;
