Numeric Rust

General-purpose N-dimensional matrix class for Rust. It links to OpenBLAS and LAPACK to make tensor operations fast (such as matrix multiplications and linear solvers). It utilizes Rust's move semantics as much as possible to avoid unnecessary copies.

Documentation

Features

Some of the completed and planned features:

• Element-wise addition, subtraction, multiplication, division
• Matrix multiplication and scalar product
• Indexing
• Slicing
• Generic (anything from Tensor<bool> to Tensor<f64>)
• Mathematical functions
• Linear solver
• Basic random number generation
• Creation macro
• Updating slices
• Saving/loading HDF5
• Strided slices
• Broadcasted axes
• Matrix inverse and SVD

Recent progress is summarized in CHANGELOG.md.

Example

#[macro_use(tensor)]
extern crate numeric;

use numeric::Tensor;

fn main() {
    let a: Tensor<f64> = Tensor::range(6).reshape(&[2, 3]);
    let b = tensor![7.0, 3.0, 2.0; -3.0, 2.0, -5.0];
    let c = tensor![7.0, 3.0, 2.0];

    let d = &a + &b;         // a copy is made
    println!("d = {}", d);

    let e = a.dot(&c);       // matrix multiplication (returns a new tensor)
    println!("e = {}", e);

    let f = a + &b;          // a is moved (no new memory is allocated)
    println!("f = {}", f);

    // Higher-dimensional
    let g: Tensor<f64> = Tensor::ones(&[2, 3, 4, 5]);
    println!("g = {}", g);
}

Output:

d =
 7 4 4
 0 6 0
[Tensor<f64> of shape 2x3]
e =
  7 43
[Tensor<f64> of shape 2]
f =
 7 4 4
 0 6 0
[Tensor<f64> of shape 2x3]
g =
...
[Tensor<f64> of shape 2x3x4x5]

Acknowledgements

Numeric Rust is primarily inspired by Numpy and borrows heavily from that project. Even the name is a play on Numeric Python. Another source of some inspiration is Torch7.
