Trait lax::QR_

pub trait QR_: Sized {
    fn householder(l: MatrixLayout, a: &mut [Self]) -> Result<Vec<Self>>;
    fn q(l: MatrixLayout, a: &mut [Self], tau: &[Self]) -> Result<()>;
    fn qr(l: MatrixLayout, a: &mut [Self]) -> Result<Vec<Self>>;
}

Required Methods

fn householder(l: MatrixLayout, a: &mut [Self]) -> Result<Vec<Self>>

Execute Householder reflection as the first step of QR-decomposition

For C-continuous array, this will call LQ-decomposition of the transposed matrix $ A^T = LQ^T $

fn q(l: MatrixLayout, a: &mut [Self], tau: &[Self]) -> Result<()>

Reconstruct Q-matrix from Householder-reflectors

fn qr(l: MatrixLayout, a: &mut [Self]) -> Result<Vec<Self>>

Execute QR-decomposition at once
