Returns the parameters the distribution was constructed with.

1) Returns the a parameter. It defines the shape of the distribution. The default value is 1.0.

2) Returns the b parameter. It defines the scale of the distribution. The default value is 1.0.

Parameters

(none)

Return value

1) The value of the a parameter.

2) The value of the b parameter.

Complexity

Constant.
