生成一个Cauchy分布。

template<class RealType = double>
    class cauchy_distribution {
public:
    typedef RealType result_type;
    struct param_type;
    explicit cauchy_distribution(result_type a0 = result_type(0.0),
        result_type b0 = result_type(1.0));
    explicit cauchy_distribution(const param_type& par0);
    result_type a() const;
    result_type b() 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;
    };
