weibull_distribution() : weibull_distribution(1.0) {} | (1) | (since C++11) |

explicit weibull_distribution( RealType a, RealType b = 1.0 ); | (2) | (since C++11) |

explicit weibull_distribution( const param_type& params ); | (3) | (since C++11) |

Constructs a new distribution object. (2) uses `a`

and `b`

as the distribution parameters. (3) uses `params`

as the distribution parameters.

a | - | the a distribution parameter (shape) |

b | - | the b distribution parameter (scale) |

params | - | the distribution parameter set |
