std::weibull_distribution
From cppreference.com
| Defined in header <random>

| template< class RealType = double > class weibull_distribution; |
(since C++11) | |
The weibull_distribution meets the requirements of a RandomNumberDistribution and produces random numbers according to the Weibull distribution:
- f(x;a,b) =
⎛a b
⎜
⎝
⎞x b
⎟
⎠a-1
exp⎛
⎜
⎝-⎛
⎜
⎝
⎞x b
⎟
⎠a
⎞
⎟
⎠
a is the shape parameter and b the scale parameter.
std::weibull_distribution satisfies RandomNumberDistribution.
