Description

gauss_distributiongauss_distributiongauss_distributionGaussDistributionGaussDistribution generates a Gaussian noise distribution. The parameter SigmaSigmaSigmaSigmasigma determines the noise's standard deviation. Usually, the result DistributionDistributionDistributionDistributiondistribution is used as input for the operator add_noise_distributionadd_noise_distributionadd_noise_distributionAddNoiseDistributionAddNoiseDistribution.
