exponential_rng()

template<typename T_inv , class RNG >

VectorBuilder< true, double, T_inv >::type stan::math::exponential_rng ( const T_inv &  beta, RNG &  rng  )

inline

Return a exponential random variate with inverse scale beta using the specified random number generator.

beta can be a scalar or a one-dimensional container.

Template Parameters

T_inv	Type of inverse scale parameter
RNG	class of random number generator

Parameters

beta	(Sequence of) positive inverse scale parameter(s)
rng	random number generator

Returns

(Sequence of) exponential random variate(s)

Exceptions

std::domain_error

if beta is nonpositive
