- For
- Rust users working with sparse design matrices
- Worth noticing
- It represents the normalized matrix as an operator, applying centering and scaling during products rather than storing centered values.
Field notes
The Rust example builds a LazyMatrix from an ndarray view, selects mean centering and standard-deviation scaling, then computes a matrix-vector product. The homepage also points to comparisons of lazy and eager APIs and benchmarks covering construction, repeated operations, and additional memory. It names faer, nalgebra, ndarray, sprs, and chunked Zarr arrays as backend options.
