Statisticsnansum Method (InArrayDouble, Int32)

public static RetArray<double> nansum(
	InArray<double> A,
	int dim = -1
)

Public Shared Function nansum ( 
	A As InArray(Of Double),
	Optional dim As Integer = -1
) As RetArray(Of Double)

Dim A As InArray(Of Double)
Dim dim As Integer
Dim returnValue As RetArray(Of Double)

returnValue = Statistics.nansum(A, dim)

Parameters

A

Type: ILNumericsInArrayDouble
Input array.

dim (Optional)

Type: SystemInt32
[Optional] Index of the dimension to operate along. If omitted operates along the first non singleton dimension (i.e. != 1).

Return Value

The array returned will have the same size as A, with the specified or first non singleton dimension reduced to the length 1. It will contain the sum of all elements along that dimension after removing NaN values respectively.

If A contains an all NaN vector along dim , the resulting sum will be 0 - not NaN! This corresponds to the sum of an empty vector.
