Rust bindings and wrappers for BLAS (Basic Linear Algebra Subprograms).
RBLAS wraps each external call in a trait with the same name (but capitalized).
This trait contains a single static method, of the same name. These traits are
generic over the four main types of numbers BLAS supports: f32
, f64
,
Complex32
, and Complex64
.
For example the functions cblas_saxpy
, cblas_daxpy
, cblas_caxypy
, and
cblas_zaxpy
are called with the function Axpy::axpy
.
Additionally, RBLAS introduces a few traits to shorten calls to these BLAS
functions: Vector
for types that implement vector-like characteristics and
Matrix
for types that implement matrix-like characteristics. The Vector
trait is already implemented by Vec
and []
types.
Add this to your Cargo.toml
:
toml
[dependencies]
rblas = "0.0.7"
and this to your crate root:
rust
extern crate rblas;
By default, the library links with blas
dynamically. To link to an alternate
implementation, like OpenBLAS, use the environment variable CARGO_BLAS
. If
you've already built the bindings, you may need to clean and build again.
export CARGO_BLAS=openblas
```rust extern crate rblas;
use rblas::Dot;
fn main() { let x = vec![1.0f32, -2.0, 3.0, 4.0]; let y = vec![1.0f32, 1.0, 1.0, 1.0];
let d: f32 = Dot::dot(&x, &y);
assert_eq!(d, 6.0);
} ```
