lazymatrix::RawColumn

LazyMatrix for Rust · 0.8.1

Source

pub trait RawColumn<F: Scalar>

A borrowed raw column supplied by a matrix backend.

for_each_stored visits every stored entry, including explicitly stored zeros. Dense implementations visit every row. Sparse implementations omit structural zeros.

Methods

affine_add_to

fn affine_add_to<V>(
    &self,
    raw_multiplier: F,
    offset: F,
    destination: &mut V
) where V: VectorViewMut<F> + ?Sized

Source

Add raw_multiplier * raw_column + offset to a dense destination.

Sparse implementations take O(nnz) when offset == 0, and O(n + nnz) otherwise. Dense implementations take O(n).
