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) = ac{alpha}{beta} (ac{x}{beta})^{alpha-1}
\xp{(-(ac{x}{beta})^alpha)} ]
- Since
C++11
