Detailed Description

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

Functor to create normal variate random numbers.

This functor encapsulates the function normal() 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

NormalRandomFunctor

(

Engine const &

generator = Engine::global()

)

Create functor for standard normal random numbers using the given engine.

That is, mean is 0.0 and standard deviation is 1.0.

NormalRandomFunctor	(	double	mean,
		double	stddev,
		Engine &	generator = Engine::global()
	)

Create functor for normal random numbers with given mean and standard deviation using the given engine.
