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
• [x] Indexing
• [x] Slicing
• [ ] Strided slices
• [ ] Updating slices
• [ ] 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;                // a copy is made
println!("d = \n{}", d);

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

let f = a + &b;                 // a is moved (no memory is 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])
