      public GaussianGenerator(NumberGenerator<Double> mean, NumberGenerator<Double> standardDeviation, Random rng)

      Creates a generator of normally-distributed values. The mean and standard deviation are determined by the provided NumberGenerators. This means that the statistical parameters of this generator may change over time. One example of where this is useful is if the mean and standard deviation generators are attached to GUI controls that allow a user to tweak the parameters while a program is running.

      To create a Gaussian generator with a constant mean and standard deviation, use the GaussianGenerator(double, double, Random) constructor instead.

      Parameters:
      mean - A NumberGenerator that provides the mean of the Gaussian distribution used for the next generated value.
      standardDeviation - A NumberGenerator that provides the standard deviation of the Gaussian distribution used for the next generated value.
      rng - The source of randomness.
    • GaussianGenerator

      public GaussianGenerator(double mean, double standardDeviation, Random rng)
      Creates a generator of normally-distributed values from a distribution with the specified mean and standard deviation.
      Parameters:
      mean - The mean of the values generated.
      standardDeviation - The standard deviation of the values generated.
      rng - The source of randomness.
