Function norm_simd 

pub fn norm_simd<F>(a: &ArrayView1<'_, F>) -> F
where
    F: Float + SimdUnifiedOps,

SIMD-accelerated L2 norm (Euclidean norm)

Computes ||x||₂ = sqrt(sum(x²))

Arguments

• a - Input array

Returns

L2 (Euclidean) norm

Examples

use scirs2_core::ndarray::array;
use scirs2_core::ndarray_ext::elementwise::norm_simd;

let x = array![3.0_f64, 4.0];
let n = norm_simd::<f64>(&x.view());
// sqrt(9 + 16) = 5
assert!((n - 5.0).abs() < 1e-14);

Use Cases

• Vector magnitude
• Normalization preprocessing
• Regularization penalty
• Gradient clipping
