Type Definition munum::Mat2

pub type Mat2<T = f32> = Matrix<T, 2, 2>;

A 2x2 matrix

Implementations

impl<T: Copy + NumAssign> Mat2<T>

pub fn det(&self) -> T

Calculates the determinant of this matrix.

Examples

let m = Mat2::<i32>::from_slice(&[1, 2, 3, 4]);
assert_eq!(m.det(), -2);

pub fn invert(&mut self) -> bool

Invert this matrix. If this matrix is not invertible, this method returns false and the matrix is unchanged.

Examples

let mut m = <Mat2>::from_slice(&[1., 2., 3., 4.]);
assert!(m.invert());
assert_eq!(*m.as_ref(), [-2., 1., 1.5, -0.5]);
