exponential_distribution
::lambda
result_type lambda() const;
Lambda
Returns the parameter
lambda
(λ) associated with the
exponential_distribution
.
This parameter represents the number of times the random events are observed by interval, on average.
This parameter is set on
construction
.
Parameters
none
Return value
The lambda parameter (λ) associated with the distribution object.
Complexity
Constant.
