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 RandomDriver()

Method Detail

getSeed

public int getSeed()

setSeed

public void setSeed(int newSeed)

randomize

public void randomize()

set random seed from time

choose

public double choose()

Returns:

random float [0..1)

choose

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)

Returns:

random int [low..high)

choose

public double choose(double low,
                     double high)

Returns:

random double [low..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)

Return a Gaussian distributed value. sigma controls narrowness of bell, xmu controls the centering of bell. Small sigmas make tight narrow bells.

qa

public int qa()

main

public static void main(java.lang.String[] args)
