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.

gleam add matrix_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)
}
