C# Class NSoft.NFramework.Numerics.Distributions.Continuous.Exponential

지수 분포 The exponential distribution is a distribution over the real numbers parameterized by one non-negative parameter. Wikipedia - exponential distribution.
The distribution will use the System.Random by default.

Users can set the random number generator by using the RandomSource property.

The statistics classes will check all the incoming parameters whether they are in the allowed range. This might involve heavy computation. Optionally, by setting Control.CheckDistributionParameters to false, all parameter checks can be turned off.
