void param( const param_type& params ); | (2) | (since C++11) |
Manages the associated distribution parameter set.
1) Returns the associated parameter set.
2) Sets the associated parameter set to params.
| params | - | new contents of the associated parameter set |
1) The associated parameter set.
2) (none).
Constant.
