Struct SimdGraphUtils 

pub struct SimdGraphUtils;

General SIMD-accelerated vector utilities for graph computations.

Implementations

impl SimdGraphUtils

pub fn axpy(alpha: f64, x: &ArrayView1<'_, f64>, y: &mut [f64])

SIMD-accelerated AXPY: y = alpha * x + y.

Arguments

• alpha - Scalar multiplier
• x - Input vector
• y - Accumulator vector (modified in place)

pub fn norm_l2(v: &ArrayView1<'_, f64>) -> f64

L2 norm of a vector using SIMD.

pub fn norm_l1(v: &ArrayView1<'_, f64>) -> f64

L1 norm of a vector using SIMD.

pub fn norm_linf(v: &ArrayView1<'_, f64>) -> f64

Linf norm (max absolute value) of a vector using SIMD.

pub fn dot(a: &ArrayView1<'_, f64>, b: &ArrayView1<'_, f64>) -> f64

SIMD dot product.

pub fn normalize_l2(v: &ArrayView1<'_, f64>) -> Option<Array1<f64>>

Normalize a vector to unit L2 norm using SIMD.

Returns None if the vector is zero.

pub fn cosine_similarity( a: &ArrayView1<'_, f64>, b: &ArrayView1<'_, f64>, ) -> f64

Compute cosine similarity between two vectors using SIMD.

pub fn difference( a: &ArrayView1<'_, f64>, b: &ArrayView1<'_, f64>, ) -> Array1<f64>

Element-wise vector difference using SIMD.

pub fn weighted_sum( a: &ArrayView1<'_, f64>, weight_a: f64, b: &ArrayView1<'_, f64>, weight_b: f64, ) -> Array1<f64>

Element-wise weighted sum: result = a * weight_a + b * weight_b.
