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.
[edit] Parameters
alpha
-
the α distribution parameter (shape)
beta
-
the β distribution parameter (scale)
params
-
the distribution parameter set
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| P0935R0 | C++11 | default constructor was explicit | made implicit |
