Detailed Description

template<class Engine = MersenneTwister>
class vigra::UniformRandomFunctor< Engine >

Functor to create uniformly distributed double-precision random numbers.

This functor encapsulates the function uniform() of the given random number Engine (usually RandomTT800 or RandomMT19937) in an STL-compatible interface.

Traits defined:

FunctorTraits<UniformIntRandomFunctor<Engine> >::isInitializer 

is true (VigraTrueType).

Constructor & Destructor Documentation

UniformRandomFunctor

(

Engine const &

generator = Engine::global()

)

Create functor for uniform random double-precision numbers in the range [0.0, 1.0] using the given engine.

That is, the generated numbers satisfy 0.0 <= i <= 1.0.

UniformRandomFunctor	(	double	lower,
		double	upper,
		Engine &	generator = Engine::global()
	)

Create functor for uniform random double-precision numbers in the range [lower, upper] using the given engine.

That is, the generated numbers satisfy lower <= i <= upper.
