extreme_value_distribution::operator()

  • Article

Returns a random value.

template<class Engine>
    result_type operator()(Engine& eng);
template<class Engine>
    result_type operator()(Engine& eng,
        const param_type& par0);

Parameters

  • eng
    The random engine.

  • par0
    The parameter package used to return the random value.

Remarks

The first member operator uses the engine eng as a source of uniformly distributed random integral values and returns floating-point values with each value x occurring with probability: Pr(x) = 1 / b * e^((a - x) / b - e^((a - x) / b))

The second member function behaves the same, except that it uses the parameters stored in par0.
