Function simd_dot 

pub fn simd_dot(a: &[f64], b: &[f64]) -> f64

SIMD-accelerated dot product with runtime feature detection.

Uses AVX2 on x86_64 (with std feature) when available, falls back to scalar otherwise.

Returns the dot product of a and b, processing up to the shorter slice’s length.

Examples

use irithyll_core::simd::simd_dot;

let a = [1.0, 2.0, 3.0];
let b = [4.0, 5.0, 6.0];
assert!((simd_dot(&a, &b) - 32.0).abs() < 1e-12);
