ExtensionMethodsargmax Method (ConcreteArrayUInt32, ArrayUInt32, InArrayUInt32, OutArrayUInt32, RetArrayUInt32, StorageUInt32, NullableInt32, OutArrayUInt32)

public static RetArray<long> argmax(
	this ConcreteArray<uint, Array<uint>, InArray<uint>, OutArray<uint>, RetArray<uint>, Storage<uint>> A,
	Nullable<int> axis = null,
	OutArray<uint> values = null
)

<ExtensionAttribute>
Public Shared Function argmax ( 
	A As ConcreteArray(Of UInteger, Array(Of UInteger), InArray(Of UInteger), OutArray(Of UInteger), RetArray(Of UInteger), Storage(Of UInteger)),
	Optional axis As Nullable(Of Integer) = Nothing,
	Optional values As OutArray(Of UInteger) = Nothing
) As RetArray(Of Long)

Dim A As ConcreteArray(Of UInteger, Array(Of UInteger), InArray(Of UInteger), OutArray(Of UInteger), RetArray(Of UInteger), Storage(Of UInteger))
Dim axis As Nullable(Of Integer)
Dim values As OutArray(Of UInteger)
Dim returnValue As RetArray(Of Long)

returnValue = A.argmax(axis, values)

Parameters

A

Type: ILNumerics.Core.ArraysConcreteArrayUInt32, ArrayUInt32, InArrayUInt32, OutArrayUInt32, RetArrayUInt32, StorageUInt32
Array to compute the indices for. This is not altered.

axis (Optional)

Type: SystemNullableInt32
[Optional] The working dimension. Default: (null) finds the maximum of the whole array.

values (Optional)

Type: ILNumericsOutArrayUInt32
[Optional] Returns the maximum values found from A also. Default: (null) maximum values are not returned.

Return Value

Usage Note

Negative dimension specifier 'axis' will be shifted into the range of valid dimension indices. -1 corresponds to the last dimension.

argmax(ConcreteArrayUInt32, ArrayUInt32, InArrayUInt32, OutArrayUInt32, RetArrayUInt32, StorageUInt32, NullableInt32, OutArrayUInt32) prioritizes NaN values over non-NaN values. I.e.: if any of the elements is NaN the respective result value will be NaN also. Conversely, nanargmax(ConcreteArrayUInt32, ArrayUInt32, InArrayUInt32, OutArrayUInt32, RetArrayUInt32, StorageUInt32, NullableInt32, OutArrayUInt32), ignores NaN values and gives the maximum among the non-NaN values, if possible. This corresponds to the behavior of ILNumerics version 4, Matlab(R) a.s.f.
