lognormal_distribution Class

Generates a log-normal distribution.

template<class RealType = double>
    class lognormal_distribution {
public:
    typedef RealType result_type;
    struct param_type;
    explicit lognormal_distribution(result_type m0 = result_type(0.0),
        result_type s0 = result_type(1.0));
    explicit lognormal_distribution(const param_type& par0);
    result_type m() const;
    result_type s() const;
    param_type param() const;
    void param(const param_type& par0);
    result_type min() const;
    result_type max() const;
    void reset();
    template<class Engine>
        result_type operator()(Engine& eng);
    template<class Engine>
        result_type operator()(Engine& eng,
            const param_type& par0);
private:
    result_type stored_a;
    result_type stored_b;
    };

Parameters

Remarks
