DistancePowerDistanceGetDistance Method

Returns the power distance between two data sets, using the current values of parameters p and r.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public double GetDistance(
	DoubleVector data1,
	DoubleVector data2
)

Public Function GetDistance ( 
	data1 As DoubleVector,
	data2 As DoubleVector
) As Double

public:
double GetDistance(
	DoubleVector^ data1, 
	DoubleVector^ data2
)

member GetDistance : 
        data1 : DoubleVector * 
        data2 : DoubleVector -> float

Parameters

data1 DoubleVector: The first data set.
data2 DoubleVector: The second data set.

Return Value

Double
The power distance between data1 and data2.

Exceptions

Exception	Condition
MismatchedSizeException	Thrown if the given data sets do not have equal lengths.

Remarks

The power distance is computed as:

Copy

distance( x, y ) = ( |xi - yi|^p )^1/r

Missing values are allowed. Pairs of elements are excluded from the distance measure when their comparison returns NaN. If all pairs are excluded, NaN is returned for the distance measure.
