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
