gamma_distribution() : gamma_distribution(1.0) {}
(1) (since C++11)
explicit gamma_distribution( RealType alpha, RealType beta = 1.0 );
(2) (since C++11)
explicit gamma_distribution( const param_type& params );
(3) (since C++11)

Constructs a new distribution object.

2) Uses alpha and beta as the distribution parameters.
3) Uses params as the distribution parameters.

Parameters

alpha - the α distribution parameter (shape)
beta - the β distribution parameter (scale)
params - the distribution parameter set
