Numeric Rust

N-dimensional matrix class for Rust 1.0. It links to OpenBLAS to give fast operations like the matrix multiplication. It utilizes Rust's move semantics as much as possible to avoid unnecessary copies.

Features

Some of the completed and planned features:

• [x] Element-wise addition, subtraction, multiplication, division
• [x] Matrix multiplication and scalar product
• [ ] Indexing
• [ ] Slicing
• [ ] Different types (currently f64 only)
• [ ] Broadcasted axes
• [ ] Matrix solver / inverse

Example

```rust use numeric::tensor::Tensor;

fn main() { let a = Tensor::range(6).reshaped(&[2, 3]); let b = Tensor::new(vec![7.0, 3.0, 2.0, -3.0, 2.0, -5.0]).reshaped(&[2, 3]); let c = Tensor::new(vec![7.0, 3.0, 2.0]);

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

let e = Tensor::dot(&a, &c);    // matrix multiplication
println!("e = \n{}", e);

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

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

} ```

Output:

d = [[ 7.00 4.00 4.00] [ 0.00 6.00 0.00]] e = [ 7.00 43.00] f = [[ 7.00 4.00 4.00] [ 0.00 6.00 0.00]] g = Tensor([2, 3, 4, 5])
