Help understanding the state of ndarrays and linalg in Rust.

• faer-rs

  29 1,215 7.9 Rust

  Linear algebra foundation for the Rust programming language

Faer is comparable to Eigen in most of their benchmarks, so they are getting closer.

• matrixmultiply

  4 202 6.0 Rust

  General matrix multiplication of f32 and f64 matrices in Rust. Supports matrices with general strides.

The matrixmultiply crate from the ndarray author (https://github.com/bluss/matrixmultiply) is one such implementation. It uses the same algorithm as the BLIS project (https://www.cs.utexas.edu/users/flame/pubs/TOMS-BLIS-Analytical.pdf) to partition the problem and exploit the cache hierarchy. It isn't as well tuned as eg. Intel MKL or BLIS, but the results are very respectable.
