Struct RotationMatrix 

pub struct RotationMatrix {
    pub dim: usize,
    pub data: Vec<f32>,
}

Orthogonal rotation matrix R (d x d) that decorrelates dimensions before PQ.

Fields

dim: usize

data: Vec<f32>

Implementations

impl RotationMatrix

pub fn identity(dim: usize) -> Self

Identity rotation (no-op).

pub fn rotate(&self, v: &[f32]) -> Vec<f32>

Rotate vector: y = x @ R.

pub fn inverse_rotate(&self, v: &[f32]) -> Vec<f32>

Inverse rotate: x = y @ R^T.
