nalgebra_blas 0.1.1

base::blas: MatrixGemm and its impls, the per-shape BLAS traits.

Readme

nalgebra_blas

The BLAS-like kernels of the static shapes (upstream nalgebra::base::blas) of nalgebra-cairo, the Cairo port of the Rust nalgebra crate on fixed::Fixed (Q32.32), built for provable game physics.

What it holds

  • base::blas: one ...BlasTrait per static shape (dotc, tr_dot, axpy, axcpy, gemv, gemv_tr, sygemv, ger, syger...) and the generic MatrixGemm, MatrixGemmTr, MatrixGemv, MatrixGemvTr, MatrixQuadform, MatrixQuadformTr with their impls.

Upstream's module paths are kept: nalgebra_blas::base::blas::MatrixGemm is nalgebra::base::blas::MatrixGemm (docs/SPLIT.md §3.1). It depends on nalgebra_core, nalgebra_types2, nalgebra_types3, nalgebra_types4, nalgebra_types5 and nalgebra_types6.

When to depend on it

Depend on nalgebra_blas (and the crates it depends on) when you need gemm, gemv, axpy or the rank updates of the static shapes without the rest of the library. It belongs to the declared closure static4_blas (static 2-4 + blas: 12.4 s / 2.88 GB on a GitHub runner over an empty consumer, budget 15 s / 3 GB); its own marginal cost over its direct dependencies is 1.4 s / 0.36 GB (12,105 lines). For upstream's whole API at upstream's paths, depend on the facade nalgebra, which re-exports every sub-crate at the 0.1.0 paths (behind its feature blas, on by default: nalgebra always depends on this crate, the feature gates its re-exports only).
