A cauchy_distribution random number distribution produces random numbers x distributed according to the probability density function
p(x|a,b)=(πb(1+(x−ab)2))−1.
template<class RealType = double> class cauchy_distribution { public: using result_type = RealType; using param_type = unspecified; explicit cauchy_distribution(RealType a = 0.0, RealType b = 1.0); explicit cauchy_distribution(const param_type& parm); void reset(); template<class URBG> result_type operator()(URBG& g); template<class URBG> result_type operator()(URBG& g, const param_type& parm); RealType a() const; RealType b() const; param_type param() const; void param(const param_type& parm); result_type min() const; result_type max() const; };
explicit cauchy_distribution(RealType a = 0.0, RealType b = 1.0);
Effects: Constructs a cauchy_distribution object; a and b correspond to the respective parameters of the distribution.
RealType a() const;
Returns: The value of the a parameter with which the object was constructed.
RealType b() const;
Returns: The value of the b parameter with which the object was constructed.
