Struct DMat

Source

pub struct DMat<S: Simd, const B: usize> {
    pub cols: Vec<Fl<DV<S>, B>>,
    pub cols64: Vec<[V8<S>; B]>,
}

Expand description

A constant (8 B) x (8 B) double-double matrix stored by columns (column j as a field over the rows), with a copy of the columns’ hi parts for the f64 lanes.

Fields§

§cols: Vec<Fl<DV<S>, B>>§cols64: Vec<[V8<S>; B]>

cols64[j][b] = cols[j].0[b].hi

Implementations§

Source §

impl<S: Simd, const B: usize> DMat<S, B>

Source

pub fn from_rows(hi: &[f64], lo: &[f64]) -> Self

from row-major (8 B, 8 B) hi / lo arrays

Source

pub fn apply<T: MatLane<S = S>>(&self, f: &Fl<T, B>) -> Fl<T, B>
