**qmat** is a simple library for 2-dimensional matrices.

## Usage

### New matrix

There are three main ways to create a new matrix.

```rust

use qmat::prelude::*;

// Creates the matrix 2x3

//     [0, 1, 2]

//     [3, 4, 5]

// The generics are the data type, the number of rows, the

// number of cols then the lenth of the data (rows * cols) 

let mat: Matrix = Matrix::new([0, 1, 2, 3, 4, 5]).unwrap();

// Or,

let mat = Matrix::<_, 2, 3, 6>::new([0, 1, 2, 3, 4, 5]).unwrap();

```

```rust

use qmat::prelude::*;

// Creates the same matrix using the analagous macro pattern.

// Automatically unwraps the errors.

let mat = matrix!(2, 3, [0, 1, 2, 3, 4, 5]);

```

```rust

use qmat::prelude::*;

let mat = matrix!([[0, 1, 2], [3, 4, 5]]);

```

Matrices can also be created using [Matrix::empty](https://docs.rs/qmat/latest/qmat/mat/struct.Matrix.html#method.empty) and [Matrix::diag](https://docs.rs/qmat/latest/qmat/mat/struct.Matrix.html#method.diag).

### Retrieving a value

#### Using a [usize; 2]

```rust

use qmat::prelude::*;

let mat = matrix!([[0, 1, 2], [3, 4, 5]]);

println!("{}", mat[[1, 1]]); // 4

```

#### Using the position struct

```rust

use qmat::prelude::*;

let mat = matrix!([[0, 1, 2], [3, 4, 5]]);

let pos = Position(0, 2);

println!("{}", mat[pos]); // 2

```

### Matrix operations

### Iterators

## Todo

* Implement mutable row and col iterators

* Implement inverting for matrices that aren't of the shape (2, 2)

* Allow indexing for anything that can be converted into [usize; 2]

* Optimise

* Add examples for matrix operations and iterators to README.md
