umontreal.iro.lecuyer.hups.F2wNetLFSR

public class F2wNetLFSR
extends DigitalNetBase2

This class implements a digital net in base 2 starting from a linear feedback shift register generator. It is exactly the same point set as the one defined in the class F2wCycleBasedLFSR. See the description of this class for more details on the way the point set is constructed.

Constructing a point set using this class, instead of using F2wCycleBasedLFSR, makes SSJ construct a digital net in base 2. This is useful if one wants to randomize using one of the randomizations included in the class DigitalNet.

Constructor and Description
F2wNetLFSR(int w, int r, int modQ, int step, int nbcoeff, int[] coeff, int[] nocoeff, int dim) Constructs a point set with 2rw points.
F2wNetLFSR(java.lang.String filename, int no, int dim) Constructs a point set after reading its parameters from file filename; the parameters are located at line numbered no of filename.
