RealType a() const;	(1)	(since C++11)
RealType b() const;	(2)	(since C++11)

Returns the distribution parameters with which the distribution was constructed.

1) Returns the a parameter. It specifies the location of the peak and is also called location parameter. The default value is 0.0.

2) Returns the b parameter. It represents the half-width at half-maximum (HWHM) and is also called scale parameter. The default value is 1.0.

Parameters

(none)

Return value

1) The value of the a parameter.

2) The value of the b parameter.

param (C++11)

gets or sets the distribution parameter object (public member function)
