描述
gauss_distributiongauss_distributionGaussDistributionGaussDistributionGaussDistributiongauss_distribution generates a Gaussian noise
distribution. The parameter SigmaSigmaSigmaSigmasigmasigma determines the noise's
standard deviation. Usually, the result DistributionDistributionDistributionDistributiondistributiondistribution is
used as input for the operator add_noise_distributionadd_noise_distributionAddNoiseDistributionAddNoiseDistributionAddNoiseDistributionadd_noise_distribution。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
