public class NiedXingSequenceBase2
extends DigitalSequenceBase2

This class implements digital sequences based on the Niederreiter-Xing sequence in base 2.

Constructor Summary

NiedXingSequenceBase2(int k, int w, int dim)
Constructs a new Niederreiter-Xing digital sequence in base 2 with n = 2^k points and w output digits, in dim dimensions.

Method Summary

void	extendSequence(int k) Increases the number of points to n = 2k from now on.
String	toString() Formats a string that contains information about the point set.

Constructor Detail

NiedXingSequenceBase2

public NiedXingSequenceBase2(int k,
                             int w,
                             int dim)

Constructs a new Niederreiter-Xing digital sequence in base 2 with n = 2^k points and w output digits, in dim dimensions. The generator matrices C_j are w×k and the numbers making the bit matrices are taken from Pirsic's site. The bit matrices from Pirsic's site are transposed to be consistent with SSJ, and at most 30 bits of the matrices are used. Restrictions: 0 <= k <= 30, k <= w, and dim <= 32.

Parameters:

k - there will be 2^k points

w - number of output digits

dim - dimension of the point set

Method Detail

toString

public String toString()

Description copied from class: PointSet

Formats a string that contains information about the point set.

Overrides:

toString in class DigitalNetBase2

Returns:

string representation of the point set information

extendSequence

public void extendSequence(int k)

Description copied from class: DigitalSequenceBase2

Increases the number of points to n = 2^k from now on.

Specified by:

extendSequence in class DigitalSequenceBase2

Parameters:

k - there will be 2^k points
