lazymatrix::SparseColumnRef

LazyMatrix for Rust · 0.8.1

Source

pub struct SparseColumnRef<'a, F>

A borrowed raw sparse column.

The view exposes the underlying matrix's stored row indices and raw values without copying. A normalized LazyColumn wrapping it has logical entries

stored row:   (value − center) / scale
implicit row: (0 − center) / scale

Thus, a centered logical column is generally dense even though the two borrowed slices contain only the underlying matrix's stored entries.
