Constructors
 NameDescription
Public methodRandGenGamma Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with order and scale equal 1.
Public methodRandGenGamma(Double) Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with the specified order. The scale parameter defaults to one.
Public methodRandGenGamma(Int32) Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with order and scale equal to one.
Public methodRandGenGamma(RandomNumberGeneratorUniformRandomNumber) Constructs a random number generator using the given delegate as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with order and scale equal to one.
Public methodRandGenGamma(Double, RandomNumberGeneratorUniformRandomNumber) Constructs a random number generator using the given delegate as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with the specified order. The scale parameter defaults to 1.
Public methodRandGenGamma(Double, Double) Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with the specified order and scale parameters.
Public methodRandGenGamma(Double, Int32) Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with the specified order. The scale parameter defaults to 1.
Public methodRandGenGamma(Double, Double, RandomNumberGeneratorUniformRandomNumber) Constructs a random number generator using the given delegate as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with the specified order and scale parameter.
Public methodRandGenGamma(Double, Double, Int32) Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a gamma distribution with the specified order and scale parameters.
