public class NiedSequenceBase2
extends DigitalSequenceBase2

This class implements digital sequences constructed from the Niederreiter sequence in base 2.

Constructor Summary

NiedSequenceBase2(int k, int w, int dim)
Constructs a new digital sequence in base 2 from the first n = 2^k points of the Niederreiter sequence, with 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

NiedSequenceBase2

public NiedSequenceBase2(int k,
                         int w,
                         int dim)

Constructs a new digital sequence in base 2 from the first n = 2^k points of the Niederreiter sequence, with w output digits, in dim dimensions. The generator matrices C_j are w×k. Restrictions: 0 <= k <= 30, k <= w, and dim <= 318.

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
