# matrix_gleam

Matrix mathematics for Gleam, inspired by portions of the Rust `glam` library.

Matrices in this library are compositions of vectors from the `vec` library (as type aliases), so many of their operations are expressed in terms of operations on `vec` types. You can build your own on top in the same way!

All contained matrices are column-major; that is, in a 2x2 matrix, the first _column_ is the `x` component of the `Vec2`.

```sh
gleam add matrix_gleam
```
```gleam
import matrix/mat3f
import vec/vec3
import vec/vec3f

pub fn main() -> Nil {
  let v = vec3.Vec3(2.2, 3.5, -0.4)
  assert v == mat3f.identity |> mat3f.mul_vec3(v)
}
```
