public class Irregular1DSet
extends IrregularSet

Irregular1DSet represents a finite set of samples of R. Note that Irregular1DSet reorders samples given in the constructor; to convert between values and indices, always use the methods valueToIndex and indexToValue.

Constructor and Description
Irregular1DSet(MathType type, float[][] samples) a 1-D irregular set with null errors, CoordinateSystem and Units are defaults from type
Irregular1DSet(MathType type, float[][] samples, CoordinateSystem coord_sys, Unit[] units, ErrorEstimate[] errors) a 1-D irregular set; samples array is organized float[1][number_of_samples]; samples need not be sorted - the constructor sorts samples to define a 1-D "triangulation"; coordinate_system and units must be compatible with defaults for type, or may be null; errors may be null
Irregular1DSet(MathType type, float[][] samples, CoordinateSystem coord_sys, Unit[] units, ErrorEstimate[] errors, boolean copy)

float	getHiX()
float	getLowX()
float[][]	indexToValue(int[] index) convert an array of 1-D indices to an array of values in R^DomainDimension
static void	main(java.lang.String[] argv)

indexToValue

public float[][] indexToValue(int[] index)
                       throws VisADException

convert an array of 1-D indices to an array of values in R^DomainDimension

Specified by:

indexToValue in interface SetIface

Overrides:

indexToValue in class IrregularSet

Parameters:

index - array of integer indices

Returns:

float[domain_dimension][indices.length] array of Set values

Throws:

VisADException - a VisAD error occurred

valueToIndex

public int[] valueToIndex(float[][] value)
                   throws VisADException

convert an array of values in R^DomainDimension to an array of 1-D indices

Specified by:

valueToIndex in interface SetIface

Overrides:

valueToIndex in class IrregularSet

Parameters:

value - float[domain_dimension][number_of_values] array of Set values

Returns:

Throws:

VisADException - a VisAD error occurred

valueToInterp

public void valueToInterp(float[][] value,
                          int[][] indices,

Overrides:

valueToInterp in class IrregularSet

Parameters:

value - An array of points. value[i][j] is the i-th coordinate of the j-th points.

indices - Indices of the neighboring samples in the set. If the j-th points lies within the set, then returned element [i][j] is the index of the i-th neighboring sample in the set; otherwise, returned array [j] is null.

weights - Weights for interpolating the neighboring samples in the set. If the j-th points lies within the set, then returned element [i][j] is the weight of the i-th neighboring sample in the set; otherwise, returned array [j] is null.

Throws:

VisADException - VisAD failure.

getLowX

public float getLowX()

getHiX

Returns:

A clone of this set with the new MathType.

Throws:
