template<typename T_loc , typename T_scale , class RNG >

VectorBuilder< true, double, T_loc, T_scale >::type stan::math::double_exponential_rng ( const T_loc &  mu, const T_scale &  sigma, RNG &  rng  )

inline

Return a double exponential random variate with the given location and scale using the specified random number generator.

mu and sigma can each be a scalar or a one-dimensional container. Any non-scalar inputs must be the same size.

Template Parameters

T_loc	Type of location parameter
T_scale	Type of scale parameter
RNG	class of random number generator

Parameters

mu	(Sequence of) location parameter(s)
sigma	(Sequence of) scale parameter(s)
rng	random number generator

Returns

(Sequence of) double exponential random variate(s)

Exceptions

std::domain_error	if mu is infinite or sigma is nonpositive
std::invalid_argument	if non-scalar arguments are of different sizes
