Function normalize 

Source 
pub fn normalize(vector: &mut [f32])
Expand description

Normalizes a vector to unit length (L2 norm = 1).

This operation modifies the vector in-place, scaling all components so that the resulting vector has a magnitude of 1.0.

§Arguments

  • vector - Mutable reference to the vector to normalize

§Behavior

  • If the vector has zero magnitude, it remains unchanged
  • Empty vectors remain unchanged

§Performance

This function performs two passes over the data (magnitude calculation and scaling). For better performance when normalizing many vectors, consider batching or using SIMD operations.

§Examples

use foxstash_core::vector::ops::normalize;

let mut v = vec![3.0, 4.0];
normalize(&mut v);
assert!((v[0] - 0.6).abs() < 1e-6);
assert!((v[1] - 0.8).abs() < 1e-6);
