ILMathdistL1 Method (InArrayInt64, InArrayInt64)

public static RetArray<long> distL1(
	InArray<long> A,
	InArray<long> B
)

Public Shared Function distL1 ( 
	A As InArray(Of Long),
	B As InArray(Of Long)
) As RetArray(Of Long)

Dim A As InArray(Of Long)
Dim B As InArray(Of Long)
Dim returnValue As RetArray(Of Long)

returnValue = ILMath.distL1(A, B)

Parameters

A

Type: ILNumericsInArrayInt64
Input points (matrix).

B

Type: ILNumericsInArrayInt64
Input point (vector).

Return Value

If B is a colum vector, the distances between B and the columns of A are calculated. The number of rows of A must match the length of vector B than. Therefore, the length of the returned vector of distances matches the number of columns of A:

A.S[1]

If B is a row vector, the distances between B and the rows of A are calculated. The number of columns of A must match the length of vector B than. Therefore, the length of the returned vector of distances matches the number of rows of A:

A.S[0]

This function is commutative, the single data point may be provided in A and the data point matrix may be provided in B as well.
