Detailed Description

template<typename _RealType = double>
class std::weibull_distribution< _RealType >

A weibull_distribution random number distribution.

The formula for the normal probability density function is:

\[
    p(x|\alpha,\beta) = \frac{\alpha}{\beta} (\frac{x}{\beta})^{\alpha-1}
                        \exp{(-(\frac{x}{\beta})^\alpha)} 
\]
