Functions
int	Math::WeightedSample (const std::vector< Real > &weights)
	Samples an integer with weighted probability. More...
int	Math::WeightedSample (const std::vector< Real > &weights, Real totWeight)
	Same as above, but the sum of all weights, W, is provided.
int	Math::CumulativeWeightedSample (const std::vector< Real > &partialSumWeights)
void	Math::RandomAllocate (std::vector< int > &num, size_t total)
	Allocates total samples within the buckets in num, roughly evenly. An O(n) algorithm where n is the number of buckets. More...
void	Math::RandomAllocate (std::vector< int > &num, size_t total, const std::vector< Real > &weights)
	Same as above, but with weights. More...
Real	Math::Sample (const Interval &s)
	Uniformly samples the given intervals.
Real	Math::Sample (const ClosedIntervalSet &s)
	Uniformly samples the interval set.
