# nalgebra-lapack [![Version][version-img]][version-url] [![Status][status-img]][status-url] [![Doc][doc-img]][doc-url]
|
|
|
|
Rust library for linear algebra using nalgebra and LAPACK.

## Cargo features to select lapack provider
|
|
|
|
Like the [lapack crate](https://crates.io/crates/lapack) from which this
|
|
behavior is inherited, nalgebra-lapack uses [cargo
|
|
features](https://doc.crates.io/manifest.html#the-[features]-section) to select
|
|
which lapack provider (or implementation) is used. Command line arguments to
|
|
cargo are the easiest way to do this, and the best provider depends on your
|
|
particular system. In some cases, the providers can be further tuned with
|
|
environment variables.
|
|
|
|
Below are given examples of how to invoke `cargo build` on two different systems
|
|
using two different providers. The `--no-default-features --features "provider"`
|
|
arguments will be consistent for other `cargo` commands.
|
|
|
|
### Ubuntu
|
|
|
|
As tested on Ubuntu 12.04, do this to build the lapack package against
|
|
the system installation of netlib without LAPACKE (note the E) or
|
|
CBLAS:
|
|
|
|
sudo apt-get install gfortran libblas3gf liblapack3gf
|
|
export CARGO_FEATURE_SYSTEM_NETLIB=1
|
|
export CARGO_FEATURE_EXCLUDE_LAPACKE=1
|
|
export CARGO_FEATURE_EXCLUDE_CBLAS=1
|
|
|
|
export CARGO_FEATURES="--no-default-features --features netlib"
|
|
cargo build ${CARGO_FEATURES}
|
|
|
|
### macOS
|
|
|
|
On macOS, do this to use Apple's Accelerate framework:
|
|
|
|
export CARGO_FEATURES="--no-default-features --features accelerate"
|
|
cargo build ${CARGO_FEATURES}

## Contributors
|
|
This integration of LAPACK on nalgebra was
|
|
[initiated](https://github.com/strawlab/nalgebra-lapack) by Andrew Straw. It
|
|
then became officially supported and integrated to the main nalgebra
|
|
repository.
