std::gamma_distribution (3) - Linux Man Pages
Defined in header <random>
template< class RealType = double > (since C++11)
Produces random positive floating-point values x, distributed according to probability density function:
where α is known as the shape parameter and β is known as the scale parameter. The shape parameter is sometimes denoted by the letter k and the scale parameter is sometimes denoted by the letter θ.
For floating-point α, the value obtained is the sum of α independent exponentially distributed random variables, each of which has a mean of β
std::gamma_distribution satisfies RandomNumberDistribution
RealType - The result type generated by the generator. The effect is undefined if this is not one of float, double, or long double.
