mdarray-linalg: linear algebra bindings for Rust mdarray

Efficient, flexible, and idiomatic linear algebra bindings (BLAS, LAPACK, etc.) to the Rust mdarray crate.

Usage

These crates are released on crates.io:

cargo add mdarray-linalg

and if you need a backend:

cargo add mdarray-linalg-blas 

Important notes:

• Use the latest version of mdarray.
• When using the BLAS backend, include openblas-src to avoid linkage errors
• When running doctests with Blas or Lapack, linking issues may occur due to this Rust issue: rust-lang/rust#125657. In that case, run the doctests with: RUSTDOCFLAGS="-L native=/usr/lib -C link-arg=-lopenblas" cargo test --doc

If you encounter linking issues with BLAS or LAPACK on Linux, one solution is to add a build.rs file and configure it to link the libraries manually. In your Cargo.toml, add:

[package]
build = "build.rs"

Then, create a build.rs file with the following content:

fn main() {
    println!("cargo:rustc-link-lib=openblas");
    println!("cargo:rustc-link-search=native=/usr/lib");
}

See docs.rs documentation for code examples and usage instructions.
