Detailed Description

Creates a discrete distribution for use within SST.

This distribution is the same across platforms and compilers.

Constructor & Destructor Documentation

◆ DiscreteDistribution() [1/2]

SST::RNG::DiscreteDistribution::DiscreteDistribution ( const double *  probs,
const uint32_t  probsCount 
)
inline

Creates a discrete probability distribution.

Parameters
probsAn array of probabilities for each outcome
probsCountThe number of discrete outcomes

◆ DiscreteDistribution() [2/2]

SST::RNG::DiscreteDistribution::DiscreteDistribution ( const double *  probs,
const uint32_t  probsCount,
SST::RNG::Random baseDist 
)
inline

Creates an exponential distribution with a specific lambda and a base random number generator.

Parameters
lambdaThe lambda of the exponential distribution
baseDistThe base random number generator to take the distribution from.

Member Function Documentation

◆ getNextDouble()

double SST::RNG::DiscreteDistribution::getNextDouble ( )
inlinevirtual

Gets the next (random) double value in the distribution.

Returns
The next random double from the discrete distribution, this is the double converted of the index where the probability is located

Implements SST::RNG::RandomDistribution.
