Detailed Description

Class NormalVariable defines a random variable with a normal (Gaussian) distribution.

This class supports the creation of objects that return random numbers from a fixed normal distribution. It also supports the generation of single random numbers from various normal distributions.

The density probability function is defined over the interval (-inf,+inf) as: where and

Constructor & Destructor Documentation

ns3::NormalVariable::NormalVariable

(

)

Constructs an normal random variable with a mean value of 0 and variance of 1.

ns3::NormalVariable::NormalVariable	(	double	m,
		double	v
	)

Construct a normal random variable with specified mean and variance.

Parameters:

	m	Mean value
	v	Variance

ns3::NormalVariable::NormalVariable	(	double	m,
		double	v,
		double	b
	)

Construct a normal random variable with specified mean and variance.

Parameters:

	m	Mean value
	v	Variance
	b	Bound. The NormalVariable is bounded symetrically about the mean [mean-bound,mean+bound]
