Description

The Weibull distribution is a real valued distribution with two parameters a and b, producing values >= 0.

It has .

weibull_distribution public construct/copy/destruct

  1. (RealType a = , RealType b = );

    Constructs a weibull_distribution from its "a" and "b" parameters.

    Requires: a > 0 && b > 0

  2. (const param_type & param);

    Constructs a weibull_distribution from its parameters.

weibull_distribution public member functions

  1. template<typename URNG> RealType (URNG & urng) ;

    Returns a random variate distributed according to the weibull_distribution.

  2. template<typename URNG> 
      RealType (URNG & urng, const param_type & param) ;

    Returns a random variate distributed accordint to the Weibull distribution with parameters specified by param.

  3. RealType () ;

    Returns the "a" parameter of the distribution.

  4. RealType () ;

    Returns the "b" parameter of the distribution.

  5. RealType () ;

    Returns the smallest value that the distribution can produce.

  6. RealType () ;

    Returns the largest value that the distribution can produce.

  7. param_type () ;

    Returns the parameters of the distribution.

  8. void (const param_type & param);

    Sets the parameters of the distribution.

  9. void ();

    Effects: Subsequent uses of the distribution do not depend on values produced by any engine prior to invoking reset.

weibull_distribution friend functions

  1. template<typename CharT, typename Traits> 
      CharT, Traits > & 
      (CharT, Traits > & os, 
                 const weibull_distribution & wd);

    Writes a weibull_distribution to a std::ostream.

  2. template<typename CharT, typename Traits> 
      CharT, Traits > & 
      (CharT, Traits > & is, 
                 const weibull_distribution & wd);

    Reads a weibull_distribution from a std::istream.

  3. bool (const weibull_distribution & lhs, 
                    const weibull_distribution & rhs);

    Returns true if the two instances of weibull_distribution will return identical sequences of values given equal generators.

  4. bool (const weibull_distribution & lhs, 
                    const weibull_distribution & rhs);

    Returns true if the two instances of weibull_distribution will return different sequences of values given equal generators.
