TensorPrimitives.IndexOfMax Method

Definition

Namespace:

System.Numerics.Tensors

Assembly:

System.Numerics.Tensors.dll

Package:

System.Numerics.Tensors v9.0.0-rc.2.24473.5

Overloads

IndexOfMax(ReadOnlySpan<Single>)	Searches for the index of the largest single-precision floating-point number in the specified tensor.
IndexOfMax<T>(ReadOnlySpan<T>)	Searches for the index of the largest number in the specified tensor.

IndexOfMax(ReadOnlySpan<Single>)

Source:

TensorPrimitives.Single.cs

Searches for the index of the largest single-precision floating-point number in the specified tensor.

public:
 static int IndexOfMax(ReadOnlySpan<float> x);

public static int IndexOfMax (ReadOnlySpan<float> x);

static member IndexOfMax : ReadOnlySpan<single> -> int

Public Shared Function IndexOfMax (x As ReadOnlySpan(Of Single)) As Integer

Parameters

x

ReadOnlySpan<Single>

The tensor, represented as a span.

Returns

Int32

The index of the maximum element in x, or -1 if x is empty.

Remarks

The determination of the maximum element matches the IEEE 754:2019 `maximum` function. If any value equal to NaN is present, the index of the first is returned. Positive 0 is considered greater than negative 0.

This method may call into the underlying C runtime or employ instructions specific to the current architecture. Exact results may differ between different operating systems or architectures.

IndexOfMax<T>(ReadOnlySpan<T>)

Source:

TensorPrimitives.IndexOfMax.cs

Searches for the index of the largest number in the specified tensor.

public:
generic <typename T>
 where T : System::Numerics::INumber<T> static int IndexOfMax(ReadOnlySpan<T> x);

public static int IndexOfMax<T> (ReadOnlySpan<T> x) where T : System.Numerics.INumber<T>;

static member IndexOfMax : ReadOnlySpan<'T (requires 'T :> System.Numerics.INumber<'T>)> -> int (requires 'T :> System.Numerics.INumber<'T>)

Public Shared Function IndexOfMax(Of T As INumber(Of T)) (x As ReadOnlySpan(Of T)) As Integer

Type Parameters

T

Parameters

x

ReadOnlySpan<T>

The tensor, represented as a span.

Returns

Int32

The index of the maximum element in x, or -1 if x is empty.

Remarks

The determination of the maximum element matches the IEEE 754:2019 `maximum` function. If any value equal to NaN is present, the index of the first is returned. Positive 0 is considered greater than negative 0.
