Detailed Description

template<typename T, class RandomGenerator>
class lass::num::DistributionNormal< T, RandomGenerator >

a normal distribution mapper (aka guassian distribution)

template arguments:

Constructor & Destructor Documentation

template<typename T, class RG>

lass::num::DistributionNormal< T, RG >::DistributionNormal ( )

construct an empty distribution.

Warning: drawing numbers from an empty distribution results in undefined behaviour, probably causing an access violation.

template<typename T, class RG>

lass::num::DistributionNormal< T, RG >::DistributionNormal	(	TGenerator &	generator,
		TParam	mean = TNumTraits::zero,
		TParam	standardDeviation = TNumTraits::one )

construct a normal distribution mapper

Parameters

generator	random number generator to be used as input. Lifespan of generator must be at least that of the distribution.
mean	mean of distribution
standardDeviation	standard deviation of distribution
