fr.cnes.sirius.patrius.tools.ephemerisComparator.RawDataComparator

All Implemented Interfaces:

Serializable

public class RawDataComparator
extends DataComparator<Double>
implements Serializable

this class is used to compare two sets of data, possibly using thresholds.

It can compute both absolute and relative deviation between the elements of the Data objects.

Method Detail

computeAbsoluteDeviation

public final ComparisonData computeAbsoluteDeviation(Data<Double> data1,
                                                     Data<Double> data2,
                                                     boolean positive)

Computes the absolute deviation between the elements of two Data object.

Parameters:

data1 - the first data set

data2 - the second data set

positive - true if absolute value of deviations, false otherwise

Returns:

a Data object that contains the deviations

Since:

1.0

computeRelativeDeviation

public final ComparisonData computeRelativeDeviation(Data<Double> data1,
                                                     Data<Double> data2,
                                                     boolean positive)

Computes the relative deviation between the elements of two Data object.

Parameters:

data1 - the first data set

data2 - the second data set

positive - true if absolute value of deviations, false otherwise

Returns:

a Data object that contains the deviations

Since:

1.0

computeAbsoluteDeviation

public static final double computeAbsoluteDeviation(double x,
                                                    double y,
                                                    boolean positive)

Computes the absolute deviation between two double precision values.

Parameters:

x - the first value

y - the second value

positive - true if absolute value of deviations, false otherwise

Returns:

a Data object that contains the deviations

Since:

1.0

computeRelativeDeviation

public static final double computeRelativeDeviation(double x,
                                                    double y,
                                                    double eps)

Computes the relative deviation between two double precision values. If one of the values is NaN or infinite, the method returns NaN.

Parameters:

x - the first value

y - the second value

eps - the threshold under which a number is considered 0

Returns:

a Data object that contains the deviations

Since:

1.0
