Gaussian Distribution

This class produces Gaussian or normal distribution with a user-provided mean and standard deviation. Optionally, a random number generator can also be provided for sampling. If a random number generator is not provided, Mersenne will be used.

Constructor​

GaussianDistribution(double mn, double sd);
GaussianDistribution(double mn, double sd, SST::RNG::Random* baseRNG);

Parameters​

  • mn (double) The mean of the distribution
  • sd (double) The standard deviation of the distribution
  • baseRNG (SST::RNG::Random*) A random number generator for sampling the distribution

getNextDouble​

double getNextDouble();

Return the next double in the distribution.

Parameters​

  • returns (double) The next double in the distribution

getMean​

double getMean();

Return the mean of the distribution.

Parameters​

  • returns (double) The mean of the distribution

getStandardDev​

double getStandardDev();

Return the standard deviation of the distribution.

Parameters​

  • returns (double) The mean of the distribution

Example​

SST::RNG::GaussianDistribution* dist = new SST::RNG::GaussianDistribution(22.5, 1.1);

double next;
next = dist->getNextDouble();
