Class RandomDriver

java.lang.Object
com.softsynth.jmsl.util.RandomDriver
public class RandomDriver
extends java.lang.Object
RandomDriver, an object of this type generates a random number sequence whose seed can be set and gotten. This is just like JMSLRandom except it can be instantiated, ie it has non-static methods. Use this when you want more than one random number sequence in a piece, where one or more of them may have the seed reset independently of the others.

      public int choose​(int high)
      Returns:
      random int [0..high)

    • choose

      public double choose​(double high)
      Returns:
      random double [0..high)

    • choose

      public int choose​(int low, int high)

    • choosePlusMinus

      public int choosePlusMinus​(int range)
      return random integer between +range and -range, inclusive

    • choosePlusMinus

      public double choosePlusMinus​(double range)
      return random double between +range and -range

    • gauss

      public double gauss​(double sigma, double xmu)
