std::chi_squared_distribution - std::chi_squared_distribution
Defined in header <random>
template< class RealType = double > (since C++11)
The chi_squared_distribution produces random numbers x>0 according to the Chi-squared_distribution:
Γ is the Gamma_function (See also std::tgamma) and n are the degrees_of_freedom (default 1).
std::chi_squared_distribution satisfies all requirements of RandomNumberDistribution
RealType - The result type generated by the generator. The effect is undefined if this is not one of float, double, or long double.
