TensorPrimitives.SumOfSquares Method

Definition

Namespace:

System.Numerics.Tensors

Assembly:

System.Numerics.Tensors.dll

Package:

System.Numerics.Tensors v9.0.0-rc.1.24431.7

Overloads

SumOfSquares(ReadOnlySpan<Single>)	Computes the sum of the square of every element in the specified tensor of single-precision floating-point numbers.
SumOfSquares<T>(ReadOnlySpan<T>)	Computes the sum of the square of every element in the specified tensor of numbers.

SumOfSquares(ReadOnlySpan<Single>)

Source:

TensorPrimitives.Single.cs

Computes the sum of the square of every element in the specified tensor of single-precision floating-point numbers.

public:
 static float SumOfSquares(ReadOnlySpan<float> x);

public static float SumOfSquares (ReadOnlySpan<float> x);

static member SumOfSquares : ReadOnlySpan<single> -> single

Public Shared Function SumOfSquares (x As ReadOnlySpan(Of Single)) As Single

Parameters

x

ReadOnlySpan<Single>

The tensor, represented as a span.

Returns

Single

The result of adding the square of every element in x, or zero if x is empty.

Remarks

This method effectively computes: Span<float> squaredValues = ...; TensorPrimitives.Multiply(x, x, squaredValues); float result = TensorPrimitives.Sum(squaredValues); but without requiring intermediate storage for the squared values.

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.

SumOfSquares<T>(ReadOnlySpan<T>)

Source:

TensorPrimitives.Sum.cs

Computes the sum of the square of every element in the specified tensor of numbers.

public:
generic <typename T>
 where T : System::Numerics::IAdditionOperators<T, T, T>, System::Numerics::IAdditiveIdentity<T, T>, System::Numerics::IMultiplyOperators<T, T, T> static T SumOfSquares(ReadOnlySpan<T> x);

public static T SumOfSquares<T> (ReadOnlySpan<T> x) where T : System.Numerics.IAdditionOperators<T,T,T>, System.Numerics.IAdditiveIdentity<T,T>, System.Numerics.IMultiplyOperators<T,T,T>;

static member SumOfSquares : ReadOnlySpan<'T (requires 'T :> System.Numerics.IAdditionOperators<'T, 'T, 'T> and 'T :> System.Numerics.IAdditiveIdentity<'T, 'T> and 'T :> System.Numerics.IMultiplyOperators<'T, 'T, 'T>)> -> 'T (requires 'T :> System.Numerics.IAdditionOperators<'T, 'T, 'T> and 'T :> System.Numerics.IAdditiveIdentity<'T, 'T> and 'T :> System.Numerics.IMultiplyOperators<'T, 'T, 'T>)

Public Shared Function SumOfSquares(Of T As {IAdditionOperators(Of T, T, T), IAdditiveIdentity(Of T, T), IMultiplyOperators(Of T, T, T)}) (x As ReadOnlySpan(Of T)) As T

Type Parameters

T

Parameters

x

ReadOnlySpan<T>

The tensor, represented as a span.

Returns

T

The result of adding the square of every element in x, or zero if x is empty.

Remarks

This method effectively computes: Span<T> squaredValues = ...; TensorPrimitives.Multiply(x, x, squaredValues); T result = TensorPrimitives.Sum(squaredValues); but without requiring intermediate storage for the squared values.
