Methods

ConditionalSelect(ReadOnlySpan<float>, ReadOnlySpan<float>, ReadOnlySpan<float>, Span<float>, float)

Performs masked SIMD operation (conditional selection) using AVX-512 or blending.

public static void ConditionalSelect(ReadOnlySpan<float> condition, ReadOnlySpan<float> trueValues, ReadOnlySpan<float> falseValues, Span<float> result, float threshold = 0)

Parameters

condition ReadOnlySpan<float>

trueValues ReadOnlySpan<float>

falseValues ReadOnlySpan<float>

result Span<float>

threshold float

DotProduct(ReadOnlySpan<float>, ReadOnlySpan<float>)

Performs vectorized dot product of two arrays with platform-optimal SIMD.

public static float DotProduct(ReadOnlySpan<float> a, ReadOnlySpan<float> b)

Parameters

a ReadOnlySpan<float>

b ReadOnlySpan<float>

Returns

float

GatherFloat32(ReadOnlySpan<float>, ReadOnlySpan<int>, Span<float>)

Advanced gather operation for sparse/indirect memory access patterns. Uses AVX2 gather when available, falls back to scalar.

public static void GatherFloat32(ReadOnlySpan<float> source, ReadOnlySpan<int> indices, Span<float> destination)

Parameters

source ReadOnlySpan<float>

indices ReadOnlySpan<int>

destination Span<float>

L2Norm(ReadOnlySpan<float>)

Computes L2 norm (Euclidean norm) of a vector using SIMD.

public static float L2Norm(ReadOnlySpan<float> vector)

Parameters

vector ReadOnlySpan<float>

Returns

float

VectorSum(ReadOnlySpan<float>)

Performs vectorized reduction (sum) with platform-optimal SIMD.

public static float VectorSum(ReadOnlySpan<float> vector)

Parameters

vector ReadOnlySpan<float>

Returns

float
