The NormalDistribution type exposes the following members.

Constructors
 NameDescription
Public methodNormalDistribution Initializes a new instance of the NormalDistribution class, using a StandardGenerator as underlying random number generator.
Public methodNormalDistribution(Generator) Initializes a new instance of the NormalDistribution class, using the specified Generator as underlying random number generator.
Public methodNormalDistribution(Double, Double) Initializes a new instance of the NormalDistribution class, using the DefaultGenerator as underlying random number generator.
Public methodNormalDistribution(Double, Double, Generator) Initializes a new instance of the NormalDistribution class, using the specified Generator as underlying random number generator.

Properties
 NameDescription
Public propertyCanReset Gets a value indicating whether the random number distribution can be reset, so that it produces the same random number sequence again.
(Inherited from Distribution)
Public propertyGenerator Gets or sets a Generator object that can be used as underlying random number generator.
(Inherited from Distribution)
Public propertyMaximum Gets the maximum possible value of normal distributed random numbers.
(Overrides DistributionMaximum)
Public propertyMean Gets the mean value of normal distributed random numbers.
(Overrides DistributionMean)
Public propertyMedian Gets the median of normal distributed random numbers.
(Overrides DistributionMedian)
Public propertyMinimum Gets the minimum possible value of normal distributed random numbers.
(Overrides DistributionMinimum)
Public propertyMode Gets the mode of normal distributed random numbers.
(Overrides DistributionMode)
Public propertyMu Gets or sets the parameter mu which is used for generation of normal distributed random numbers.
Public propertySigma Gets or sets the parameter sigma which is used for generation of normal distributed random numbers.
Public propertyVariance Gets the variance of normal distributed random numbers.
(Overrides DistributionVariance)

Remarks
The implementation of the NormalDistribution type bases upon information presented on Wikipedia - Normal distribution and the implementation in the Communication Networks Class Library.
C#
Return normal (Gaussian) distributed random deviates
with mean "m" and standard deviation  "s" according to the density:

                                          2
                     1               (x-m)
 p   (x) dx =  ------------  exp( - ------- ) dx
  m,s          sqrt(2 pi) s          2 s*s
