Detailed Description

This abstract class is the base class of all discrepancy classes.

All derived classes must implement the abstract method compute(points, n, s).

Constructor & Destructor Documentation

Discrepancy() [1/5]

Discrepancy	(	double	points[][],
		int	n,
		int	s
	)

Constructor with the \(n\) points points[i] in \(s\) dimensions.

points[i][j] is the \(j\)-th coordinate of point \(i\). Both \(i\) and \(j\) start at 0. One may also choose points = null in which case, the points must be set later.

Discrepancy() [2/5]

Discrepancy	(	double	points[][],
		int	n,
		int	s,
		double []	gamma
	)

Constructor with the \(n\) points points[i] in \(s\) dimensions and the \(s\) weight factors gamma[ \(j\)], \(j = 0, 1, …, (s-1)\).

points[i][j] is the \(j\)-th coordinate of point \(i\). Both \(i\) and \(j\) start at 0. One may also choose points = null in which case, the points must be set later.

Discrepancy() [3/5]

Discrepancy	(	int	n,
		int	s,
		double []	gamma
	)

The number of points is \(n\), the dimension \(s\), and the \(s\) weight factors are gamma[ \(j\)], \(j = 0, 1, …, (s-1)\).

The \(n\) points will be chosen later.

Discrepancy() [4/5]

Discrepancy

(

PointSet

set

)

Constructor with the point set set.

All the points are copied in an internal array.

Discrepancy() [5/5]

Discrepancy

(

)

Empty constructor.

The points and parameters must be defined before calling methods of this or derived classes.

Member Function Documentation

compute() [1/4]

double compute

(

double

points[][]

)

Computes the discrepancy of all the points of points in maximum dimension.

Calls method compute(points, points.length, points[0].length, gamma).

compute() [2/4]

double compute	(	double []	T,
		int	n
	)

Computes the discrepancy of the first n points of T in 1 dimension.

Copies the points in an array of arrays and calls method compute(double[][], n, 1). It should be reimplemented in subclasses for better efficiency.

compute() [3/4]

double compute

(

double []

T

)

Computes the discrepancy of all the points of T in 1 dimension.

Calls method compute(T, T.length, gamma[0]).

compute() [4/4]

double compute

(

PointSet

set

)

Computes the discrepancy of all the points in set in the same dimension as the point set.

All the weights \(=1\).

setPoints() [1/2]

void setPoints	(	double	points[][],
		int	n,
		int	s
	)

Sets the points to points and the dimension to \(s\).

The number of points is \(n\).

setPoints() [2/2]

void setPoints

(

double

points[][]

)

Sets the points to points.

The number of points and the dimension are the same as in points.

sort()

static DoubleArrayList sort ( double []  T, int  n  )

static

Sorts the first \(n\) points of \(T\).

Returns the sorted points. Warning: \(T\) is sorted also.
